The Development Squad may have left it late to defeat Everton and maintain their 100 per cent start to the season on Monday night, but U21s boss Nick Haycock felt the final 2-1 scoreline was fully justified.

Sebastian Lletget's well-taken 89th minute strike eventually settled the contest after Everton threatened to frustrate the visitors through Luke Garbutt's stunning equaliser.

West Ham hit the crossbar three times and failed to take advantage of a first half penalty, but would not be denied and Haycock had praise for their tenacity in seeing the job through to the end.

The three point haul was the second from two Barclays U21 Premier League fixtures at the start of the campaign, ensuring Haycock would travel back to London as a happy man.

"We thoroughly deserved the victory," he told West Ham TV. "I'm delighted because we've played two fantastic football clubs in Aston Villa and Everton in the first week of the season [and won both games].

"Credit to Alan Stubbs' Everton team tonight. They're a young side and they tried to play the game in the right way. It was a good contest.

"I think that as the game went on we started to assert our authority. I said to the lads at half time that I felt we could play higher up the pitch and we did in the second half. Consequently we got on the ball and played the type of football I know we can.

"A mixture of fantastic defending, blocks, clearances and the woodwork [was denying us] and you just think it might get away from you.

"Elliot Lee hit the bar at 1-0, and if it goes 2-0 you think it might kill their energy, but then the kid Luke Garbutt scores a fantastic strike.

"Sebby's tucked a great goal away at the end to win it and we showed great energy levels. He had a good pre-season and got that first team experience - he's got two goals in two games now and it's pleasing."

Having taken the lead their play merited thanks to Callum Driver's cross-shot midway through the second period, the young Hammers' heads may have dropped when Garbutt levelled just six minutes later.

That they remained strong and came again was testament to the togetherness amongst the Development Squad group, according to Haycock.

He explained: "They're a good group of lads, I keep saying it but the football club's a great place to be at the moment. There are some fantastic people in there, Sam's driving the Club towards the Olympic Stadium and you saw the first team performance at the weekend.

"The character in there, the professionalism we're showing on and off the pitch, that's the staff I've got with me, the group of us that drive hard every day and hopefully the rewards are that the teamship comes out on the pitch. I think it did tonight, I was delighted to see every one of the players celebrate together. I think that shows the camaraderie there."

The U21s have only conceded one goal in their two games to date - Garbutt's thunderbolt at Everton - and Haycock wants to see that good defensive work continue.

He added: "I've been pleased with us defensively in the two games because the precedent the football club sets is to keep clean sheets to give yourself a chance of winning the game.

"We're working hard on the defending, and Martyn Margetson, the goalkeeping coach with the first team, did a presentation on the importance of set plays because we conceded one or two in pre-season,

"The block on the free kick was something we've worked on. we'd seen Everton score a goal against Wolves with it so we were pleased with that. It's the transition through the Club, all playing the game in the same manner. That's what's going to help them try and assert their position within Sam's squad. We're a unit working together."
