Evans, Soyuncu, Tielemans & Maguire were all on international duty over the summer and all play tonight
Correct. But that's not what I was saying.
All the senior players apart from James who missed out tonight played internationals in the summer. Which suggests to me that they're a bit behind on their fitness. Presumably the three involved today turned up fitter than the others.
I'll put it another way. All the senior players who didn't play internationals during the summer are playing today, apart from James.
