Manchester City host Chelsea at the Etihad Stadium on Sunday looking to pile more misery on the Blues following their opening day draw with Swansea.
The champions were lucky to escape their opener at Stamford Bridge with a point following Thibaut Courtois' red card early in the second half as they held on for a 2-2 draw against the spirited Swans.
Jose Mourinho's criticised his club's own medical staff this week after they went on to treat Eden Hazard late on, reducing the team to nine players in the dying minutes. His controversial comments have unsettled the camp, with doctors Eva Caneiro and Jon Fearn having reportedly been suspended by the club.
Whether the backroom drama has any effect on the squad's performance remains to be seen and an early trip to thier most realistic rivals for the title promises to be a stern test of the club's resolve.
Mourinho will, however, be boosted with a fully-fit squad to take to Eastlands should playmaker Oscar (knock) come through a late fitness test as expected, but Courtois will begin a three-match suspension, giving new-signing Asmir Begovic a chance in the Blues' goal.
Similarly, City have a largely unchanged squad from the one that eased past West Brom 3-0 in their opener on Monday night and boss Manuel Pellegrini may have full-back Gael Clichy back amongst the substitutes after overcoming an ankle injury.
The Chilean is stll without new signing Fabian Delph (hamstring), who is yet to make his debut for the Citizens following his move from Aston Villa, though the England internatinal is expected be fit for City's trip to Everton in a week's time. Fernando (groin) remains sidelined.
City will be favourites to win the clash and should the midfield trio of Yaya Toure, David Silva and Fernandinho replicate their performance in the win over the Baggies, Mourinho may need to use all his tactical expertise to come away with a result.
