Novak Djokovic hopes Boris Becker is able to live a relatively normal life once the six-time grand slam champion has served his prison sentence.

Becker, who became the youngest ever male major singles champion when he won Wimbledon in 1985, was sentenced last week after being found guilty of four charges relating to violations of the United Kingdom Insolvency Act.

The 54-year-old declared bankruptcy in 2017 but was found to have hidden assets and loans in order to avoid paying his debts, which amounted to around £50million.

Becker coached Djokovic earlier in the Serbian's career and the world number one is shattered for the German.

"Heartbroken for him," Djokovic told a news conference ahead of the Madrid Open.

"He is a friend, a long-time friend, a coach for three, four years. Someone I consider close in my life, he has contributed a lot to my success in my career.

"I was just heartbroken. I don't know what to say more than that. It's [not] getting into details of the verdict, because I'm not in a position to do that, but as his friend, super sad for him and there's not much that you can say.

"I just hope that he will go through this period that he has to be in jail and that when he comes out he's being able to live his life as, I don't know if you can use the word normal, because his life is definitely changing. For anybody going to prison, especially for that long of a time.

"So I don't know how things will turn out for him. I just pray for him. I hope things will be well in terms of his health, his mental health, because that's probably going to be the most challenging part."

Former world number one Andy Murray, however, has little sympathy for Becker.

"I feel sorry that he's in that situation, but I also feel sorry for the people that he's affected with his decisions as well and what's happened to them," said Murray. who faces Dominic Thiem in his opening match in Madrid.

"I hope he's okay and that he learns from his mistakes. But I didn't have a particular emotion about it.” 

Naomi Osaka joined several other big names in falling to a second-round exit at the Madrid Open, although Emma Raducanu cruised to a routine straight-sets win over Marta Kostyuk.

Four-time grand slam winner Osaka crashed to a resounding 6-3 6-1 loss to Spain's Sara Sorribes Tormo, exiting her first tournament on clay since the 2021 French Open, where she withdrew citing mental health issues.

Osaka, who had posted an underwhelming 20-15 record on the surface prior to this week, looked uncomfortable throughout and appeared to struggle with a leg injury during a disappointing second set display.

The 24-year-old was not the only high profile player to be on the receiving end of a shock during a day of drama in the Spanish capital, as several of the competition's seeds failed to secure places in the last 16.

Another home favourite, Garbine Muguruza, fell to a resounding loss of her own as Anhelina Kalinina raced to a 6-3 6-0 victory over the seventh seed, while sixth seed Danielle Collins was thrashed 6-1 6-1 by Canadian Bianca Andreescu.

Fourth seed Maria Sakkari was the highest-ranked player in action, and although the world number five won the first set of her clash with Daria Kasatkina, the Greek eventually fell to a 3-6 6-3 6-1 loss, while 2021 US Open runner-up Leylah Fernandez went down 6-4 6-4 to Jil Teichmann.

One big name who did make comfortable progress, however, was Fernandez's US Open conqueror Raducanu, who eased to a 6-2 6-1 win over Kostyuk to set up a last-16 encounter with another Ukrainian in Kalinina. 

The 19-year-old, who has been quoted as saying she believes clay could prove to be her best surface in the future, was delighted with her victory and enjoying the tournament after dropping just one game in the second set.

"I'm definitely happy with my performance," Raducanu said on court. "Marta's a great opponent - I knew it was going to be a really tough battle. I went out there trying to be really aggressive and it paid off.

"It's my first clay court season and I'm really enjoying it. Madrid is such a cool city and it's got such a great vibe about it. I definitely want to try and stay here for as long as possible."

There were victories for John Isner and Dan Evans as the Madrid Open got up and running on Sunday.

Big-serving American Isner overcame Filip Krajinovic 7-6 (10-8) 6-4 and will face either Cameron Norrie or Kwon Soon-woo in the round of 32.

Isner is joined in the next round by Evans, who eased past Federico Delbonis 6-3 6-4 to set up a last-32 meeting with either Roberto Bautista Agut or Jenson Brooksby.

Fellow Briton Jack Draper also enjoyed a straight-sets victory, edging out Lorenzo Sonego 6-4 6-3 to book a clash with number six seed Andrey Rublev, who received a bye.

Monday's action will see wildcard Andy Murray face Dominic Thiem and 10th seed Jannik Sinner take on Tommy Paul.

Rafael Nadal remains confident that he will be fully fit in time for this month's French Open, despite still suffering from a "very disabling" rib injury.

The 35-year-old has been sidelined since sustaining a cracked rib during the Indian Wells Masters in March.

However, Nadal confirmed last week he intends to make his return to action on home soil at the Madrid Open next week.

And the Spaniard, who won a record 21st grand slam at the Australian Open in January, expects to be ready for Roland-Garros later this month.

"I have three weeks," he said on Saturday. "I trust that the daily training will help me to get ready.

"Here the demand [in high altitude in Madrid] is maximum, but what can be done is going to be done.

"The most important thing is to be healthy, but I think that going to Paris I'm on time. Three weeks is enough time to get competitive."

He added: "I have trained very little, because the rib is very disabling and also very painful. I had two very bad weeks and afterwards it has been very, very disabling.

"I haven't been able to do practically anything, but it's here, at home, in Madrid."

Thirteen-time French Open winner Nadal will face either Alexander Bublik or Miomir Kecmanovic in the second round of the Madrid Open.

The third seed is on a collision course with highly rated compatriot Carlos Alcaraz in the quarter-finals at the Caja Magica.

Simona Halep blew Paula Badosa away with a Madrid Open masterclass to reach the round of 16 on Saturday.

Second seed Badosa had no answer to the brilliance of Halep in her homeland as the relentless Romanian won 6-3 6-1 at the Caja Magica.

Unseeded two-time grand slam champion Halep took just an hour and 17 minutes to eliminate Badosa, breaking three times in the first set and twice in the second.

Halep, in a new era with Patrick Mouratoglou in her corner, won 84 per cent of points when she landed her first serve in, staying in the hunt to win this tournament for a third time with the French Open on the horizon.

The former world number one will face Coco Gauff for a place in the quarter-finals following the American's 6-1 2-6 6-4 late-night defeat of Yulia Putintseva.

Gauff, the 14th seed, racked up 10 double faults and was pushed all the way by Putintseva, but served out the match after securing a third break in a tight final set.

Ons Jabeur earlier advanced into the third round at the expense of Varvara Gracheva, recovering from a second-set bagel to win 7-5 0-6 6-4.

Jabeur faces a meeting with Belinda Bencic after the Swiss dispatched Karolina Muchova 6-3 4-6 7-5.

Victoria Azarenka came from a set down to beat Tamara Zidansek 3-6 6-1 6-3 to set up a meeting with Amanda Anisimova, who also had to come from behind to dispatch Petra Martic 3-6 6-3 6-2.

Ekaterina Alexandrova and Marie Bouzkova also progressed in the Spanish capital.

Carlos Alcaraz has learned never to give up after facing Rafael Nadal, with the pair on a collision course to meet again in next week's Madrid Open quarter-finals.

Alcaraz has enjoyed a hugely impressive season to date, having last week added the Barcelona Open to the titles won in Rio de Janeiro and Miami already in 2022.

Following on from that triumph in Catalonia, Alcaraz – who turns 19 next week – became the youngest male player to break into the top 10 since Nadal 17 years ago.

He boasts a record of 23-3 this year, one of those defeats coming at the hands of Spanish great Nadal in the semi-finals of Indian Wells in March.

That encounter lasted over three hours, with Nadal digging deep in California to prevail 6-4 4-6 6-3, only to lose in the final to Taylor Fritz.

Nadal was clearly troubled by injury during his defeat to Fritz and has subsequently taken a break to recover from a rib problem.

The pair are set to collide once again in Madrid next week should they both come through their second and third-round matches.

Speaking ahead of the draw being made on Friday, Alcaraz revealed he has taken inspiration from facing Nadal, who won a record 21st Grand Slam at the 2022 Australian open.

"I learned about the fighting spirit, of never giving up," the teenager told Spanish talk show El Hormiguero.

"Many people will have also seen the Australian Open match, he was losing and came back almost miraculously.

"From that match against him [at Indian Wells] I get the fighting spirit, never give up and fight until the last ball."

Top seed Novak Djokovic is also in Alcaraz and Nadal's side of the Madrid Open draw, while Andy Murray and Dominic Thiem will meet in the pick of the first-round clashes.

Naomi Osaka was encouraged by her 2022 clay-court debut, winning her opening match at the Madrid Open against Anastasia Potapova.

The former world number one has not played on the red dirt since the 2021 French Open, where she withdrew citing mental health issues.

Heading into this week in Madrid, Osaka had an underwhelming 20-15 record on clay, with each of her grand slam successes coming on hard courts.

But the 24-year-old has spoken of adjusting her approach and learning from clay king Rafael Nadal – and the early signs were positive.

She needed just over an hour to defeat Potapova 6-3 6-1 on Friday and said: "I'm honestly trying to be more positive with myself.

"This year I came a week early to train on red clay, so I'm just trying to give myself more chances to do better.

Osaka added: "To be able to do it in two sets, for me, it's a really good starting block. 

"I think today for me it was really fun, just being able to be back on the clay and not taking those moments for granted."

Fellow hard-court major champions Emma Raducanu and Bianca Andreescu also won their openers, although the latter required three sets to eventually coast past Alison Riske 6-4 3-6 6-0.

Raducanu will play another 19-year-old in the second round, with the US Open champion paired with Marta Kostyuk after getting over a slightly slow start to thrash Tereza Martincova 7-6 (7-3) 6-0.

Fourth seed Maria Sakkari overcame a scare, meanwhile, ending her losing run at three matches by coming from behind to defeat Madison Keys in three sets.

"Overall, it was a very positive match to get myself back in the winning feeling," the Greek said.

Amanda Anisimova celebrated her fifth career top-10 win by beating Aryna Sabalenka again at the Madrid Open.

The 20-year-old American would have headed into Thursday's match-up full of confidence having also defeated the world number four in Charleston earlier this month.

And again Anisimova came out on top, this time at a tournament where Sabalenka was the defending champion.

Sabalenka is now 0-4 against Anisimova, losing three times on clay, with this the underdog's first ever victory in Madrid.

A 6-2 3-6 6-4 triumph was sealed in an hour and 55 minutes, with Anisimova relishing the opportunity to take on one of the sport's foremost stars once more.

"It's always enjoyable to accept the challenge, even when it's a tough match, and push yourself and see how far you can go," Anisimova said.

"I enjoy these matches, even though they're very tough – especially when you get to win them."

While Anisimova can look forward to facing Petra Martic in round two, hers was not the only upset win, with Karolina Pliskova and Jelena Ostapenko also ousted.

Pliskova lost in straight sets to fellow Czech Marie Bouzkova, as Ostapenko went down in three to Ekaterina Alexandrova.

Simona Halep and next opponent Paula Badosa both came through unscathed, though, as did Belinda Bencic, Coco Gauff and Ons Jabeur.

Jabeur's 11-9 first-set tie-break success against Jasmine Paolini was the closest any of that quintet came to dropping a set on day one.

Emma Raducanu hailed Torben Beltz as "one of the nicest people I've met", despite deciding to split from the German coach.

The US Open champion parted company with Beltz on Tuesday after just five months together.

The duo began working together in November but have now split as the world number 11 plots the way forward ahead of the French Open and Wimbledon.

"Torben is a great guy. I really enjoyed my time with him on and off the court," Raducanu said while preparing for the Madrid Open on Wednesday. 

"He is one of the nicest people I've met, so obviously it was a tough one to split with someone like that.

"But I feel like right now I'm very comfortable with my current training. I'm feeling very confident in what I'm doing and how I'm working.

"I feel like over the last few weeks it's definitely become more apparent and especially as I've spent more time on the tour playing more matches against these top opponents, that I kind of understand what I feel like I need more of.

"I think Torben has been great for me because when I wanted someone with tour experience, I think for my first six months on the tour, it was very valuable."

The 19-year-old has recently enjoyed her best week of the season, winning back-to-back matches at the Stuttgart Open, before putting in a respectable performance in defeat to world number one Iga Swiatek.

Beltz is the third coach to move on from working with Raducanu in the last 12 months. She swapped Nigel Sears for Andrew Richardson, who worked with her at the US Open, before deciding to bring in Beltz, who previously worked with Angelique Kerber and Donna Vekic.

Raducanu is scheduled to face Czech player Tereza Martincova on Friday in Madrid and will be assisted by Iain Bates at the tournament, the long-serving head of women's tennis at the Lawn Tennis Association.

Naomi Osaka believes teen tennis star Carlos Alcaraz has rejuvenated excitement around the ATP Tour, while she labelled Rafael Nadal as an inspiration ahead of the Madrid Open.

Alcaraz needed just 67 minutes to defeat Spanish compatriot Pablo Carreno-Busta 6-3 6-2 at the Barcelona Open last Sunday, claiming his third title of the season after wins in Rio de Janeiro and Miami.

The 18-year-old has surged to a career-high ninth in the world rankings, Alcaraz becoming the youngest player to crack the top 10 since fellow Spaniard Nadal achieved that feat at the same age in 2005.

Coincidentally, Nadal also broke into the top 10 after success on the same day (April 25) at the Barcelona Open and the pair will next compete in Madrid in the ATP 1000 Masters event, which starts on Sunday.

Former women's world number one Osaka revealed she is keen to cast an eye over the duo in the Spanish capital, where she faces a qualifier in the first round, as she hailed the impact Alcaraz has had.

"I feel like he's genuinely made everyone excited about the ATP and I haven't seen that in a very long time," Madrid Open wildcard Osaka said of Alcaraz, who boasts an impressive 23-3 record in the 2022 season.

"I'm not even really thinking about his age, like every time someone brings up his age, I'm like, 'Oh wow, I forget, that's so cool'.

"I think just his game style, just how pumped he is, how I feel like I'm watching him learn with every tournament.

"I don't know what his ranking was last year here, but I've watched almost every tournament that he's played, the US Open when he played [Stefanos] Tsitsipas and just to see the growth I think is really exciting for everyone."

Osaka has won all four of her grand slam titles on hard courts, but the 24-year-old will now search for clay-court success in Madrid.

Japanese Osaka has spent time preparing in Majorca, where she has used 13-time French Open winner Nadal as an inspiration, given his expertise on clay courts.

"I think I stole one of the things that he did and I've been practising it recently," she said of Nadal, who holds the record for most men's grand slam titles with 21 major triumphs to his name.

"It'll either go really good or really bad. There's like no in between. But I think as I've been doing it, it's been going pretty well.

"Honestly I've been wanting to watch the really good clay-court players practice because I feel like I'm the type of person that learns really fast if I see it up close and honestly it's a bit of a waste to have all these really good professional tennis players and not watch them."

Osaka suffered a second-round exit at the Indian Wells Masters in March, impacted by abuse from a heckler in the crowd, but rebounded by making the final in Miami, where she lost to world number one Iga Swiatek.

However, Osaka is looking to use the experience at Indian Wells, where she was reduced to tears by a spectator reportedly shouting "Naomi, you suck", as a learning curve to develop.

"I feel like there are a lot of moments in my career that are like extremely sad for me at the time but I kind of later look back on it and I think to myself, 'Well that really made me grow as a person, and even though I really hated the experience, I'm glad it happened to me'," she added.

"For me, that's one of those moments. I wish it didn't happen, but also I'm glad that it did.

"I feel like it prepared me for a lot of things that may or may not happen, but it's kind of like one of those things you have in your back pocket as experience."

World number one Iga Swiatek will not play the Madrid Open after suffering a shoulder injury.

The Pole is in stunning form, having won four titles in a row after prevailing in the Stuttgart Open last time out.

Before that, the 20-year-old – whose winning streak stands at 23 matches – had lifted the trophy at the Qatar Ladies Open, Indian Wells and Miami Open.

"After intense last weeks and winning four titles in a row, it's time to take care of my arm that has been fatigued since the Miami Open and I haven't had a chance to handle it properly," Swiatek, the 2020 French Open champion, wrote in a statement posted to Twitter.

"I need a break from playing so intensively in order to treat my arm well and that's why, unfortunately, I have to withdraw from the Mutua Madrid Open. 

"My body needs rest. I'm going to take some time to prepare for Rome and Paris. See you soon there.

"Hopefully, I will play in Madrid many times in the future – I'm looking forward to it."

Swiatek was due to be top seed in the Spanish capital.

Rafael Nadal plans to make his return from injury in his homeland at the Madrid Open next week.

Nadal has been sidelined since suffering a cracked rib during the Indian Wells Masters last month.

The 21-time grand slam champion on Tuesday revealed he has decided to make his ATP Tour comeback at the Caja Magica.

He posted on social media: "Despite preparation being difficult, I really want to play at home since the opportunities are few.

"[I want] To try to do it in the best possible way. See you in Madrid."

Taylor Fritz consigned Nadal, a five-time champion at the Madrid Open, to his first defeat of the year in the final at Indian Wells.

The Australian Open champion was visibly struggling to breath during that match after sustaining the injury during a semi-final victory over fellow Spaniard and heir apparent Carlos Alcaraz. The 35-year-old's 2022 record so far stands at 20-1.

Nadal's return is set to make his comeback just three weeks before he will be hoping to start his bid to win a 14th French Open title at Roland Garros.

Matteo Berrettini could miss the French Open after the world number six was forced to withdraw from three tournaments as he continues to recover from minor hand surgery.

The Italian progressed to the Wimbledon final in 2021 and started the new season in encouraging fashion as he reached the Australian Open semi-finals, where he was well-beaten by eventual winner Rafael Nadal.

However, the 25-year-old has seemingly struggled from then on, with his next best performance coming in Rio – where he made the last eight – as he limped to a 9-6 record so far in 2022.

Further difficulties followed for Berrettini after he sustained an injury to his right hand late in March, forcing him to withdraw from the Miami Open before undergoing a "minor operation".

Berrettini provided another update on Instagram on Thursday, revealing he would not feature at the Monte-Carlo Masters, scheduled to start later this week, or the Madrid Open and Italian Open at the start of May.

The latter tournament in Rome begins just two weeks before the second grand slam of the year, leading to concerns that Berrettini may not feature at Roland Garros.

"UPDATE – following advice from the medical experts, my team and I have decided that it is crucial I do not put time pressure on my recovery process," he posted.

"We have therefore decided I should withdraw from the Monte-Carlo, Madrid and Rome tournaments to ensure I give myself the proper amount of time to return at my highest level.

"Withdrawing from these events, particularly Rome, was an extremely tough decision, however it is the right one to ensure many more years of competing at the highest level for the biggest trophies.

"Thanks very much for all the support. My recovery process is on track and I look forward to seeing you on-court soon."

Alexander Zverev ended a three-year wait for an ATP Masters 1000 title as he rallied to beat Matteo Berrettini in the Madrid Open final on Sunday.

The German had to do it the hard way at La Caja Magica over the past week, having previously seen off five-time winner Rafael Nadal and Dominic Thiem en route to the showpiece.

He was in a spot of bother against his Italian opponent at the end of a gripping first set that Berrettini took in a tie-break, Zverev's efforts in coming back from 5-0 down and earning a set point ultimately for nothing.

Berrettini eventually sealed the lead with his fourth set point but Zverev played with renewed focus at the start of the second, taking full advantage of a succession of mistakes with the score at 4-4 to force a decider.

Zverev's greater endurance in rallies then paid dividends early in the third as he broke to go 3-2 up, and Berrettini only won one more game as the German triumphed 6-7 (10-8) 6-4 6-3 to win the tournament for a second time.

Speaking afterwards, he said: "It is great [to win this title], especially after losing my last three finals I played at Masters 1000 events. This is definitely special and I just want to enjoy this one.

"[Berrettini's] game style showed it all. I didn't play anybody this week that can serve 235[km/h] on clay and serve 230km/h kick serves.

"It definitely was a different match and I am extremely happy right now."

On competing at the Internazionali d'Italia next, he added: "Rome is also an event I like and enjoy, so I hope I can perform [in] the same way as I did here and we will see how it goes there. I feel awesome."

This was the first time Zverev has beaten three or more top-10 players in a single competition since his ATP Finals victory in 2018.

Matteo Berrettini will take on Alexander Zverev in the Madrid Open final on Sunday after overcoming Casper Ruud 6-4 6-4 in the last four. 

Eighth seed Berrettini has enjoyed a superb debut tournament in the Spanish capital, the 25-year-old dropping just one set on his way to becoming the first Italian to make the Madrid Open final. 

Berrettini, who won the Serbia Open last month, is just the third Italian ATP Masters 1000 finalist since the series was established in 1990, after Fabio Fognini and Jannik Sinner. 

"It's a great, unbelievable feeling, especially coming from Monte Carlo where I wasn't feeling that good," Berrettini said in quotes reported by the ATP website. 

"I won in Belgrade and now I'm in the final, so I'm really looking forward to playing against Sascha [Zverev]. I hope I enjoy it tomorrow the way I enjoyed tonight.

"I saw him [Zverev], he's playing really good. He's solid. He moves well. For his height, he's really good. He serves well. I mean, he's in the final. He beat Rafa [Nadal] and Dominic [Thiem], probably the best players on clay.

"It's going to be a challenging match, but I'm in the finals. I guess the best two guys are going to play each other."

Berrettini returned supremely throughout Saturday's match, nullifying Ruud's usually potent serve, and believes his aggressive approach was key to victory.

"My serve is my weapon, but today I think I returned a lot and I put pressure on him," Berrettini said. "I was just playing more aggressive. He's kind of like me, he likes to run around the forehand and play with spin. But I guess today I was playing better than him.

"The other time he beat me, so it's always a great fight against him. He reached three semi-finals in a row so he was feeling confident. I guess that's why I'm maybe even more happy with my win today."

In the earlier semi-final, Zverev followed up his famous win over home favourite and 20-time grand slam champion Rafael Nadal in the previous round by defeating Dominic Thiem.

Austrian Thiem had won the last four meetings between the two, including in last year's Australian Open semi-final and the US Open decider, where he came from two sets down to win in an incredible fifth-set tie-break.

However, Zverev was not to be denied this time, a 6-3 6-4 result keeping him on course for a repeat of his 2018 triumph at the event in the Spanish capital.
