De Zerbi admits to Billy Gilmour 'mistake' after Moises Caicedo and Alexis Mac Allister claim
Gilmour played in a deeper midfield role – alongside Pasca Gross – and helped Albion wallop a woeful Wolves team, thanks to two goals each from Gross, Deniz Undav and Danny Welbeck.
"Mac Allister and Moises Caicedo are a very high level and it’s difficult for Gilmour to make a competition,” said De Zerbi after the match.
"Gilmour was the best player on the pitch. After the game I must admit possibly in the past I have made some mistakes with him and Undav, because I did not give them possibility to play. But for me it is difficult to decide to play without Mac Allister, Solly March, Mitoma and Moises Caicedo it is difficult."
Gilmour has made just 11 appearances for Albion since his £9m move from Chelsea last summer but the 21-year-old was pleased to take his chance on a memorable day at the Amex Stadium.
"I took my opportunity,” Gilmour said to BBC Five Live, “It's hard to fill Alexis and Moises' job but I just had to take my opportunity. When they've played I've studied them and what they do in my position. When I've been in training I've done it. To get the opportunity to try that today, it was good
"We were absolutely gutted about Wembley and then on to Nottingham, maybe it was still on us a bit. We knew we had to put on a performance and I think every single one of us was brilliant. I need to keep focusing on myself, help the team when called upon. We want to finish as high as possible."
