The 24-year-old's game-changing substitute appearance against Bournemouth and another good week of training at Cobham has seen the England international replace Pedro Neto on the left wing.

The other changes sees Enzo Fernandez, who missed the trip to Bournemouth through illness, come into the midfield in place of Renato Veiga, and Tosin Adarabioyo start at centre-back, with Axel Disasi dropping to the bench.

That means Robert Sanchez is likely to be protected by Wesley Fofana at right back, Tosin and Levi Colwill in the middle and Marc Cucurella on the left.

Moises Caicedo lines up alongside Fernandez, who will captain the team, with Cole Palmer in a more advanced position and flanked by Sancho on the left and Noni Madueke on the right.

Nicolas Jackson continues to lead the line, with Christopher Nkunku ready to make an impact from the bench once again following his match-winner against the Cherries.

There is plenty of attacking firepower among the substitutes once again, with Nkunku joined by Kiernan Dewsbury-Hall, Joao Felix, Mykhailo Mudryk and Pedro Neto.
