Galatasaray v Chelsea preview

David Luiz and John Obi Mikel have travelled for Chelsea's Champions League last-16 first-leg tie at Galatasaray on Wednesday night.

The pair missed Saturday's match with Everton through injury but have travelled to Istanbul, as has Oscar despite being substituted at half-time with an ankle complaint.

January additions Nemanja Matic and Mohamed Salah are cup-tied having already played in the Champions League this season, while Marco van Ginkel is continuing his rehabilitation from his serious knee injury.

Meanwhile, Galatasaray head coach Roberto Mancini expects Didier Drogba and Wesley Sneijder to give absolutely everything when they line up against former manager Jose Mourinho.

"Didier was an important man and an important player for Chelsea," Mancini said.

"Wesley won the Champions League under Mourinho. I think they have a good relationship but tomorrow for 90 minutes I think they will be enemies.

"After that they can go and have dinner together. But for 90 minutes I think they will play not 100 per cent, but more because we need Wesley and Didier to play very well tomorrow."
