Who will be captain?

For the first two pre-season matches Cesc Fabregas was given the captain's armband, however last season's vice-captain Cesar Azpilicueta began the game against Arsenal in Dublin and he skippered the match.

With club captain Gary Cahill still not fully back with the squad the armband will be up for grabs once again and it is likely that Azpilicueta will get the nod once more.

There have been reports that Eden Hazard is set to be given the captain's role full-time, but the Belgian is also not back in training just yet and so the competition is

Will Willian start?

It has been a pretty complicated summer for Willian and things got even more odd after he could not return back to England after having 'passport issues'.

The Brazilian was supposed to be returning to training at the beginning of the week, but only returned to Cobham on Wednesday afternoon before linking up with the rest of the squad when they returned from Dublin.

With the impressive performances of Callum Hudson-Odoi and Pedro in pre-season it is unlikely Willian will stat, but will Sarri have a trick up his sleeve?

Does Callum Hudson-Odoi get the nod?

He has been one of the bright sparks of the summer and Callum Hudson-Odoi could well get his chance to shine at Wembley in the Community Shield.

The 17-year-old has shown no fear so far and his stock is certainly growing with the Blues set to offer him more playing time with the first team and a long-term contract.

If he can put in a good performance against the Premier League champions then he could be in for another start when the league gets under way the following week.

Who starts at centre-back?

Ethan Ampadu started the first two pre-season matches with David Luiz, while Antonio Rudiger started the Arsenal game with the Brazilian in Dublin.

All three games the Blues have looked pretty solid and with Andreas Christensen also knocking on the door, Sarri is going to have to see where he can fit in his defenders.

The starting XI is going to be a keen indication of the direction that Sarri wants to go and whether or not Luiz is fighting his way back into the starting team.
