Chelsea head coach Mauricio Pochettino could make just the one change to his side for Tuesday's EFL Cup semi-final second leg with Middlesbrough at Stamford Bridge.

The Blues suffered a 1-0 defeat in the first leg at the Riverside Stadium, so they will have to come from behind to advance to the final of the tournament.

Chelsea have not been in action since recording a 1-0 win over Fulham in the Premier League on January 13, and the London club have no fresh fitness problems.

Ben Chilwell made his return from a long-term hamstring issue against Fulham, but Pochettino will want to be cautious when it comes to his fitness, so he could likely receive more minutes off the bench here.

Armando Broja found it difficult to make his mark last time out, so there could be a change in the final third of the field, with Cole Palmer potentially going through the middle.

Broja's withdrawal would open up a position which could be filled by Noni Madueke, with Raheem Sterling and Conor Gallagher also featuring in forward areas.

Nicolas Jackson remains unavailable for selection, with the striker in action for Senegal at the Africa Cup of Nations.

Meanwhile, Wesley Fofana, Reece James, Marc Cucurella, Romeo Lavia, Christopher Nkunku, Robert Sanchez and Lesley Ugochukwu are all still out through injury.

Chelsea possible starting lineup: Petrovic; Gusto, Disasi, T Silva, Colwill; Caicedo, Fernandez; Madueke, Gallagher, Sterling; Palmer
