England manager Gareth Southgate believes he has enough attacking talent at his disposal to not have to rely on one or two key players heading into next summer's European Championships.

Victory against the Czech Republic in Prague on Friday night will assure the Three Lions of their place in the tournament – where the group stage, semi-final and final will take place on home soil at Wembley.

England have blown away their Group A competition so far, scoring 19 goals from four qualifiers – including a 5-0 victory over the Czechs in March.

England are starting to build a strength in depth that is the envy of many a nation.

Such quality means in-form Leicester midfielder James Maddison arrived at his third international camp without a cap to his name – a wait that will continue after having to return to his club on the eve of the Czech Republic clash.

"It's been a difficult week for James, really," Southgate told talkSPORT.

"He still had a bit of the ankle problem that he had pre the Liverpool game with Leicester.

"And then he has fallen ill over the last couple of days, so he wasn't going to be able to train and we decided the best thing was to send him back to his club."

Asked if he had a chance he could have played a part against the Czechs or Bulgaria, Southgate said with a laugh: "Not looking at how he was this morning, no!

"Again, no point travelling with the rest of the team ill as well, so that was one of the issues.

"But he hasn't trained all week, he wouldn't have trained until Saturday at the earliest and I don't think he'd have been in a fit state for Monday."
