Rob Edwards admits Luton must quickly improve after their Premier League debut ended in a thumping 4-1 defeat at Brighton.

Just nine years on from being a non-league side, the newly-promoted Hatters were taught a punishing lesson on their first return to top-flight action since relegation from the old First Division in 1992.

Carlton Morris’ 81st-minute penalty gave Town hope of snatching something at the Amex Stadium after Joao Pedro’s spot-kick added to Solly March’s first-half header.

But, despite some encouraging signs, they were second best on the south coast and ultimately suffered a resounding loss following late finishes from Seagulls substitutes Simon Adingra and Evan Ferguson.

“We have to do it our way,” said manager Edwards. “We have got a plan, we’ve had that over the last decade or so and had a lot of success.

“We’re now going into what’s probably going to be the biggest challenge the club’s had. We know the scale of the challenge. We’re going to have some tough days.

“I don’t want anyone to be happy about losing football matches – we’re certainly not.

“I was pleased with stuff I saw today. I know we’re going to get better. But we’ve got to get better quickly.”

March nodded the hosts ahead nine minutes before the break before Brighton’s £30million record signing Pedro slotted home from 12 yards, having been brought down by Luton captain Tom Lockyer.

Morris’ successful spot-kick, after Jacob Brown’s cross struck the elbow of Lewis Dunk, looked to have set up a tense finale.

But an inexplicable error from Pelly Ruddock Mpanzu allowed Albion debutant Adingra to swiftly restore the hosts’ two-goal advantage before fellow substitute Ferguson added another deep into stoppage time.

Edwards, who felt both penalty decisions were “harsh”, was left to rue his side’s mistakes.

“I thought we were right in the game at 1-0 and at 2-1 but we shot ourselves in the foot,” he said.

“We made a couple of clear errors in the build up to the third goal and we got punished and at this level you do get punished.

“It shows the ruthless nature of the league.”

Brighton set aside Moises Caicedo’s ongoing transfer saga to launch their first campaign to feature European football in commanding fashion.

Build up to the contest was dominated by news of Albion accepting a British record transfer fee of around £111million from Liverpool for the absent Ecuador midfielder amid reports he would prefer to join Chelsea.

Seagulls boss Roberto De Zerbi, who handed debuts to James Milner and Mahmoud Dahoud, in addition to goalscorers Pedro and Adingra, also lost Alexis Mac Allister to Liverpool during the summer, while Levi Colwill returned to parent club Chelsea.

The Italian warned it will take his team time to hit the heights of last season, which brought a club-record sixth-placed finish, and does not view Dahoud as a direct replacement for Caicedo.

“Dahoud is a great player for us because he’s specific for our idea of football, for our style of play,” he said.

“But we lost different characteristics because Dahoud is different from Moises Caicedo.

“We played well, not one of the best games in my time, but we need much time to reach the same level, the same quality of play of last season.

“We won a very tough game. I’m really pleased.”

Luton boss Rob Edwards will fulfil a dream when he sends his team into Premier League action for the first time at Brighton on Saturday.

Edwards took charge at Kenilworth Road in November last year and guided a club which less than a decade earlier had been plying its trade in non-league football back into the top flight after a 31-year absence.

Life since victory in the Sky Bet Championship play-off final has been something of a whirlwind, with the Hatters busily preparing for their latest – and perhaps biggest – challenge on and off the pitch, but Edwards admits he will feel a huge sense of pride when the dream finally becomes a reality.

He told a press conference: “I’m really proud. It’s hard because you don’t always think about it, you just think about what’s next and don’t always have time to reflect.

“It’s been an aim of mine for long time. I think most people would agree the Premier League is the highest level.”

The game at the Amex Stadium could see skipper Tom Lockyer make his first competitive appearance since collapsing on the pitch early in the play-off final, the result of a heart scare which has since been addressed by surgery.

Edwards added: “This is extremely important and special for Tom. That day was made special by knowing he was OK.

“It was the most scared I’ve ever been during a football game. Health is the most important thing and it’s great to have him back.

“He’s had his own journey as well – he was in the National League and now leading his team out in the Premier League.”

Edwards’ hand has been strengthened since promotion by the arrival of nine summer signings, perhaps the most eye-catching of them former Everton and England midfielder Ross Barkley, and there could be several debuts, particularly with Jordan Clark, Dan Potts, Gabe Osho and Reece Burke all on the casualty list.

Excitement levels are understandably high, but Edwards knows there is a long and tough season ahead.

He said: “We’ve got a big season ahead and it’s been a long time coming since the final kick at Wembley. The elation turns quite real and now we feel ready.

“The fans are the most important people at any football club. They are the most important to me, they’re here before us and they’ll be here after us.

“They’ve been through some really bleak times in the past, so hopefully they can enjoy these moments because they deserve it.”

Rob Edwards’ delight at Luton ending their 31-year wait for Premier League football was nothing compared to the relief he felt at the news captain Tom Lockyer was all right.

Saturday’s Sky Bet Championship play-off final went the distance at a packed Wembley, where the Hatters rallied after their skipper’s worryingly collapse early on.

Jordan Clark put Luton into a deserved lead that Coventry midfielder Gustavo Hamer cancelled out in the second half, with the match ending 1-1 after 90 minutes and extra-time.

Joe Taylor saw a winner ruled out just before spot-kicks, with Fankaty Dabo’s sudden-death miss sealing a 6-5 shoot-out triumph that propelled Luton back into the top-flight for the first time since 1992.

The dramatic triumph means the Hatters will welcome Manchester City and Co just nine years after facing the likes of Salisbury and Hyde in the Conference Premier.

Luton boss Edwards said: “I felt a bit numb. I just made sure I shook Mark’s hand and his staff.

“I don’t want to be that guy that just starts running off and celebrating before I’ve seen the other manager.

“I just felt very numb. I still do. It hasn’t sunk in quite yet. It might take a few days, but it’s great. It does feel good.

“It was mixed because of Locks (Lockyer), that’s why I couldn’t really go for it celebrating.”

This is a day that will live long in the memory of anybody connected to Luton, whose players held a Lockyer shirt throughout the celebrations.

The Hatters captain collapsed when running back to defence in the early stages of the final, leaving the field on a stretcher and being taken to hospital for tests.

Luton confirmed Lockyer was “responsive and talking to his family”, with his dad posting an image of him in a hospital bed celebrating the shoot-out win.

Edwards cried with delight when he saw that image and hopes to soon celebrate with the much-loved skipper.

“If we can we will (see him in hospital),” he said of Lockyer, who is expected to be kept in overnight. “But I don’t want to get in the way and if I’m not allowed then I won’t.

“If I’m allowed I would love to go and see him, but then I think we’re so tight as a group that I’m not sure if 40-odd people are allowed to go and see him in hospital.

“We will have to check on that, but I’m just so thankful that he’s OK because that’s all that matters.

“I wasn’t really able to enjoy any celebration at the end because all I cared about was Locks.”

As for Coventry, it was a heartbreaking end to a memorable season.

Bottom of the table in October and taken over at the start of the year, boss Mark Robins was agonisingly close to leading the Sky Blues from League Two to the top flight.

“Firstly, congratulations to Luton because once the game is over and done with you’ve got to congratulate the winners,” the long-serving Coventry boss said.

“They’ve come out on top today, however tight the game may have been.

“Congratulations to them and their supporters. I think they have been outstanding all season and good luck to them moving forward.

“I think for us, certainly the opposite of their joy is pain.

“You certainly feel a bit of pain, but once that pain starts to dissipate in however long it takes for it to go, we’ve got to reflect on what an unbelievable achievement it’s been just to even be here today in a play-off final.

“The division is very, very tough as we all know and unfortunately we couldn’t make that next step.”

Rob Edwards was happy to extend Luton’s unbeaten run to 14 games after a much-changed side were held to a goalless Sky Bet Championship draw by Hull.

The Hatters boss swapped eight of his players with an eye on Saturday’s play-off semi-final first-leg clash against Sunderland, but those selected kept a 20th clean sheet of the season.

Edwards said: “Today was about resting key players, let’s be honest.

“It was about making sure we didn’t risk anyone unnecessarily and it was about giving some players some game time as over the next couple of games, if they’re needed, we want people up to speed, so I think it was twofold and overall it was a successful day.

“I want to say well done to (Hull manager) Liam Rosenior and what they’ve done this season as well because he’s building a good style there and they’re difficult to go and press at times.

“For some of the lads who haven’t played that much, to do a lot of double runs and a lot of pressing was good and also when we had the ball, especially in the first half, we showed some good control, and were brave with it.

“We did create one or two decent chances and moments but the game fizzled out a little bit towards the end.”

A quiet first half saw Allahyar Sayyadmanesh’s shot deflect onto the post for Hull, before Joe Taylor’s header drew a great save from visiting keeper Matt Ingram.

Adama Traore was denied by Luton stopper James Shea and Hatters substitute Luke Berry saw his chip from just inside the visitors’ half drop narrowly over the bar.

Tigers boss Rosenior said: “The final game sums up where we are.

“We played some breathtaking football at times, I was pleased with the first two-thirds of our game in terms of our build-up, we caused problems, they had to change everything, which is what teams are having to do against us.

“But when we got into the final third into some unbelievable positions, it just fizzled out, and that’s no disrespect to our players, I’ve got no strikers.

“In those critical moments against very good teams you need that cutting edge and that’s something I’m going to work really, really hard in the summer to address.

“They had one chance where Matty’s made a really good save from the header from a cross, I can’t remember another real threatening moment in the game for us.

“There’s a lot of positives to build on, anyone who understands the game can see I’ve got a group of players who completely understand the way we want to play.

“We’re building, so there’s a lot to be excited about.”

Watford have appointed Slaven Bilic as head coach after sacking Rob Edwards just 10 Championship matches into his reign.

Edwards only took over at Vicarage Road at the end of last season, leaving Forest Green Rovers to replace Roy Hodgson following the Hornets' relegation from the Premier League.

Watford relieved Edwards and his assistant Richie Kyle of their duties on Monday and swiftly confirmed Bilic had taken the hot seat, signing an 18-month contract – subject to securing a work permit.

The former Croatia defender had been out of work since leaving Beijing Guoan in January but will be the Championship club's fifth boss in less than a year.

Bilic, who was promoted with West Brom in 2019-20, takes over a side 10th in the table, just one point off the play-offs.

"As with all decisions taken by the board, I believe this change to be in the best interests of the club," said Watford owner Gino Pozzo.

"We felt Rob had enough time to show us the identity of his team; however, performances haven't reflected our hopes and ambitions.

"Now we must move forward, and, in Slaven Bilic, we have secured the services of an experienced coach who has recent experience of promotion to the Premier League."

Claudio Ranieri and Hodgson had spells in charge of Watford last season after Xisco Munoz was fired in October.
