England will take on Scotland at Wembley Stadium in London in their second Euro 2020 Group D game on Friday.
Gareth Southgate’s side kicked off their European Championship campaign with a 1-0 victory over Croatia at Wembley last weekend.
Manchester City attacking midfielder Raheem Sterling scored the only goal of the match in the 57th minute when he turned in a wonderful ball from Leeds United midfielder Kalvin Phillips.
United central defender Maguire missed the match against Croatia due to a high ankle sprain.
However, the 28-year-old has said that he is now fit to face Scotland.
Maguire told Sky Sports: “I feel good, I’ve been training now. Obviously the injury was a setback club football wise.
“Internationally I wanted to come into this with a lot of games under my belt with full fitness, but I feel good. I’m back available, been training and I’m looking forward to it.”
