The 22-year old has failed to impress in recent outings for the Three Lions.
The Spurs striker struggled to get involved in Saturday’s opening fixture against Russia and doubts are surfacing over his form and fitness after less than convincing showings in his most recent England appearances.
England succumbed to a last-gasp Russian equaliser after another Spurs man, Eric Dier, had given the Three Lions the lead with a powerful free-kick.
The Tottenham striker has played a tremendous amount of football since his emergence a little over two years ago – including the Under-21 European Championships last summer – and his work load may well be catching up with him.
He remains England’s most natural finisher however, and his return to form could be crucial if there is to be any sustained European adventure this summer.
