Chelsea return to action on Tuesday night when they square off against Ajax at Stamford Bridge in the Champions League.

Despite an opening-game defeat to Valencia, the Blues sit in top spot in Group H after back-to-back victories over Lille and Ajax respectively.

However, ahead of the reverse fixture with the Dutch giants, Frank Lampard has a number of selection dilemmas towards the end of a busy period for his squad.

Here, Sports Mole rounds up the latest injury and suspension list for Chelsea ahead of the meeting in West London.

Status: Minor doubt
Type of injury: Groin
Possible return date: November 5 (vs. Ajax)

Having taken no risks on Kante at the weekend, Lampard must now decide whether to include him from the start on Tuesday night. While the initial plan may have been to play the Frenchman, Jorginho's domestic suspension may lead to an appearance on the bench for the World Cup winner.
