Having kicked off Group D with a 1-0 win against World Cup semi-final foes Croatia before drawing 0-0 with oldest rivals Scotland, a partially-filled Wembley will welcome the Czech Republic on Tuesday evening.
Gareth Southgate’s men are well placed to progress and know a Wembley return in the last 16 will be be secured by beating the pool-topping Czechs, who Maguire is hoping to get his first Euro 2020 minutes against.
The Manchester United captain missed the end of the club season with the high ankle sprain sustained in early May and made the England bench for the first time against Scotland.
“I’m feeling good,” Maguire said. “Obviously (with) the ankle injury, it’s getting stronger, I’m getting more confident.
“The more sessions I do, the more games I play, I’m sure I’ll get more confidence and that’s the thing with these type of injuries.
“I think it’s just about building the confidence. It’s all stable now and I’m available and I’m ready to go.
“Any Euro match is really important to go out there and try and win the football match.
“The boys have put ourselves in a great position in the group – four points from two games – although obviously we want to win every football match so we’d like to be on six.
“But it’s still in a strong position and now it’s another big game against the Czechs and one we’re looking forward to and we go there and try and get three points.”
