Middlesbrough earned their first Sky Bet Championship win at the Riverside Stadium since December by beating 10-man Norwich 3-1.

The Canaries started the game on top and took the lead through Ashley Barnes, but the evening quickly took a turn when Borja Sainz was sent off in the 30th minute.

Boro levelled through Marcus Forss and Emmanuel Latte Lath put them ahead just before half-time.

Lukas Engel added a third in the second half to wrap up victory as Norwich missed the chance to move into the play-off places.

Norwich dominated the opening stages and tested the Boro defence early on when Sainz unleashed a curling effort just around the post.

They nearly had the opener in the 13th minute when a great ball released Dimitris Giannoulis down the left and the full-back found Barnes, who had a first-time strike palmed behind by goalkeeper Seny Dieng.

The early pressure paid off as the visitors took the lead in the 17th minute when Gabriel Sara picked out Barnes on the break inbetween the Boro defence and although the striker stumbled to the floor on his first go, he was able to stick a leg out on the ground to roll the ball past Dieng.

Norwich were reduced to 10 men when Sainz was tackled by Jonny Howson and the winger was shown red after flicking a boot out at the Boro captain.

Boro soon took advantage of the extra player on their first real attack of the game when Forss levelled in the 37th minute. Engel fired the ball into the box for Latte Lath, but the subsequent clearance reached the Finnish forward, who stabbed home from close-range.

The hosts took the lead just six minutes later when Matt Clarke’s cross fell to an unmarked Latte Lath, who easily tucked the ball into the bottom left corner.

Boro continued to threaten early in the second half with some dangerous crosses from both flanks. Angus Gunn made a quick stop to deny Riley McGree’s effort from a tight angle before Howson curled the ball over the crossbar from a free-kick.

Michael Carrick’s side extended their lead out of nowhere in the 62nd minute as Luke Ayling’s pin-point cross from the right found Engel at the far post, who smashed the ball first time underneath the goalkeeper.

McGree then forced Gunn to make a great punch from his powerful strike and substitute Anfernee Dijksteel had a chance saved from close range.

Boro retained possession well in the final stages and nearly had a fourth, but Engel was denied by a quick clearance.

Middlesbrough boss Michael Carrick has told his players to embrace the challenge of walking into the lion’s den at Chelsea with a place in the Carabao Cup final at stake.

Boro head coach Carrick saw his team secure a 1-0 first-leg lead at the Riverside Stadium on Wednesday evening, which will send them to Stamford Bridge on January 23 with something to defend.

The Sky Bet Championship promotion hopefuls had to endure a tide of pressure on their own pitch to emerge with a clean sheet, and they can expect an onslaught on a night when a repeat would send them to Wembley.

However Carrick, whose side lost 1-0 to Chelsea’s Premier League counterparts Aston Villa in the FA Cup third round at the weekend, said: “It’s embracing it.

“The last two games the boys have coped very, very well with Villa at the weekend and tonight, this being different because it’s obviously a lot further on in the competition and there was much more of an opportunity in this one with the expectations, the hope, the challenge that they faced.

“I couldn’t have hoped or asked for anything more. I keep saying the next one is a totally different one, it’s a new challenge totally.

“The boys will be ready for it and we’ll be ready to perform. We’ll look forward to it and embrace the challenge because it’s an unbelievable challenge and position that we find ourselves in.”

Hackney’s 37th-minute strike, which came after Isaiah Jones had made the most of Dan Barlaser’s fine through ball, ultimately settled a game in which Mauricio Pochettino’s expensively-assembled side dominated possession, but failed to make the most of the chances they created with Cole Palmer passing up no fewer than three himself.

Enzo Fernandez and Moises Caicedo alone cost in excess of £220million, but along with Conor Gallagher, got little change out of a Boro midfield of Hackney, Barlaser and Jonny Howson to leave Carrick purring.

Asked if it was his best night yet as a manager, the 42-year-old former Manchester United and England midfielder said: !It’s as proud as I’ve been, I have to say again, of the players.

“Knowing what they’ve put in and how close a group they are and seeing the stadium supporting the lads right to the end when they needed that bit of help for the last 10 minutes or so, standing there and seeing that made me hugely proud, so it was a good night for that, a really good night for that and hopefully we can create some more of them in the future.”

Pochettino was measured after a disappointing night on Teesside, during which he admitted the Blues had been punished both for their mistakes and their profligacy in front of goal.

The Argentinian said: “I am disappointed because I think we deserved a different result, but sometimes you don’t play well and you win.

“For us, it’s like we need to play well, we need to score goals. We play well, but sometimes we are not clinical enough and sometimes we are punished. That is the process in this moment we are in.

“Always when you are building a team, this kind of scenario is tough because you not only need to play well, but you need to deserve and have some luck.”

Middlesbrough boss Michael Carrick believes his side had to “suffer” to earn a 1-0 win against Chelsea in the Carabao Cup semi-finals.

Hayden Hackney capitalised on missed Chelsea chances, scoring in the 37th minute to hand Boro a valuable advantage going into the reverse fixture at Stamford Bridge on January 23.

His goal came after already-depleted Boro were forced into two early changes, with Emmanuel Latte Lath and Alex Bangura taken off with injury in the opening 20 minutes.

They defended well to ensure they are now one leg away from the final of the competition they won back in 2004 and Carrick urged his side to enjoy the victory.

He said post-match: “Listen, it’s very special.

“There’s totally two sides to this one: there’s the game tonight and what we had to go through and suffer a little bit to find a way to win, and there’s obviously the fact that there’s another game.

“I have to credit the players and celebrate their performance and effort, because it’s not easy at all to beat a team like that with the quality that they’ve got and to suffer the kind of injuries that we had as well early on – as if we didn’t have enough injuries to start with.

“Tonight was a really special night, the atmosphere, Hayden scoring, it was such a good night for us, so we’ve got to take that as a one-off and enjoy that to be honest. The second leg is a whole new ball game and we know what we’re walking into and he challenges we face.”

Dan Barlaser’s long pass played Isaiah Jones in behind Levi Colwill to cross into Hackney, who stuck out a leg to stab past Djordje Petrovic.

Carrick said: “Honestly, it couldn’t happen to a nicer lad.

“He’s everything we could ever hope for in a player – he’s humble, he’s hard-working, he’s hugely talented, obviously, and great to work with.”

Chelsea boss Mauricio Pochettino believes his side were “not clinical enough” as they wasted a trio of brilliant chances in the first half.

Cole Palmer fired wide just before Hackney put Boro ahead then had two more chances, firing over the bar after Tom Glover spilled Enzo Fernandez’s effort before failing to beat the keeper after cutting in from the right.

Pochettino said: “I think we made some mistakes in the first half and we were punished for that.

“We created big chances and we didn’t score, we were not clinical enough, that is so clear.

“We have to credit of course Middlesbrough, it’s the first 90 minutes in the first half of the tie.

“We are losing 1-0 but in two weeks we are going to have the second tie and we need to be positive we can win the game and go to the final.”

Pochettino also refuted suggestions Chelsea players had been booed off the pitch by their visiting fans.

“The fans were reacting with the fans, with Middlesbrough fans, not with our players,” he added.

“Our fans were fantastic as they support us but I think it was Thiago (Silva) and some players, what I hear is they were trying to calm our fans because I think there was a problem between the fans, not between our fans and our players.”

Mauricio Pochettino bemoaned Chelsea’s profligacy following their shock 1-0 loss at Middlesbrough in the first leg of their Carabao Cup semi-final.

The Premier League side dominated at the Riverside Stadium but squandered a host of chances, with Cole Palmer particularly wasteful.

Hayden Hackney’s first-half goal earned the Sky Bet Championship hosts a slender advantage ahead of the return meeting at Stamford Bridge in a fortnight’s time.

“We had too many chances to score where we didn’t score – that is football,” Blues boss Pochettino told Sky Sports.

“Of course we are disappointed. It is the first half of the tie. We have another 90 minutes at Stamford Bridge and we have to be positive.

“We made some mistakes and we were punished for that.”

Some of Chelsea’s travelling fans reacted angrily to the defeat at full-time.

“If we assess the performance, overall we were the better side, we create more chances, we have clear chances,” continued Pochettino.

“But we didn’t score and we were not clinical and that has happened a lot this season – so many games we didn’t win because we weren’t clinical enough.”
