England boss Gareth Southgate insists he is "not on a moral crusade" over James Maddison's casino visit.
The Leicester playmaker earned a call-up to the England squad this week, despite the fallout from him visiting a casino after withdrawing from the last squad with the flu.
While Southgate refused to punish Maddison, he warned that he wants only "high-performance, low maintenance" players in his Three Lions squad.
"I didn't feel the need to make a special case to call him," said Southgate. "I wanted to see whether we would be selecting on form.
"I think it would be dangerous territory for me to go on a moral crusade over something that I don't think was a good decision but was in his own time and we had released him from the squad.
"I'm not perfect and a lot of the players that we selected have had their moments, so I didn't think this was one to hinder him in terms of selection, but it's not a good situation for a player when we're talking about him in Sofia, and talking about him here and he's yet to get on the pitch for us.
"So, that's the challenge. You want to be high-performance, low-maintenance. I am prepared to work with players who are more difficult but you're more likely to back those players if they've scored a winner for you and sweated blood for you, and that's the bond you build with those players over a longer period of time."
