Cameron Toshack has said that his Swansea U21's side will be in for tough game tomorrow night against Coventry City at the Liberty Stadium.
Toshack told the South Wales Evening Post: "It will be tough, their league form is not as good as they would like but they have done well in this competition.
"They have scored 15 goals and won every time in their five games. They played two academy teams and scored seven goals across those two games, so we are fully aware of the task facing us and it will be one of the hardest games of the season.
"But we are looking forward to it, the lads have conducted themselves really well and to be the last development team in the competition out of all the quality groups that entered is a really good achievement and we are looking forward to this.
"It is massive for us, some of the big Premier League teams and their academies have been involved, and we are last man standing and representing development football if you like, and we want to take the chance with both hands.
"The progress this team has made has been fantastic, (joint-coach) Gary Richards and myself have worked with the boys for three years and it has been fantastic to be a part of.
"We have won 16 of the last 18 games, which for any group is a great return.
"We were delighted with the turnout for our last game, in fact whenever we have turned out at the Liberty or at Landore we have been pleased with the support we got and hopefully we have given people their money's worth.
"It's a great experience for these young men to play in front of larger crowds, it gives them more experience and we encourage as many people as possible to come down and watch.
"I know Coventry have asked for a 1,000 tickets so they will bring a big crowd and we don't want the opposing team to have more voice at our home stadium, and we hope people can come out and support our team."
