Unfortunately for Basel, they say lightning never strikes twice. Since that opening Champions League matchday defeat Chelsea have won all three of their European games, and it's hard to see them making the same mistakes again on their trip to St. Jakob-Park.

José Mourinho's team are currently topping Group E with nine points, and, having beaten nearest competitors Schalke 04 both home and away, seem to be cruising into the knockout stages. Basel still have a slim chance of progressing, currently sitting only a point in arrears of Schalke. However, with games against Chelsea and Schalke still to come, they're probably Europa League-bound.
For this match, the Swiss side will be without Chilean midfielder Marcelo Díaz, who picked up a rib injury on international duty, and defender Behrang Safari. For Chelsea, the long-term injured Marco van Ginkel is still unavailable, alongside Fernando Torres and the ineligible Michael Essien.
