Maurizio Sarri has told Victor Moses to improve tactically to secure Chelsea future.
The Chelsea boss admitted he is unsure whether Moses can adapt enough to fit into his tactical blueprint at Stamford Bridge.
Moses has made six appearances but only two in the Premier League under new manager Sarri.
Asked if Moses still have future at the club, Sarri replied: ‘I don’t know; he has to improve.

‘Moses is more suitable for playing like a wing-back than like a winger or a full-back.’
Only Wolves have used fewer players than Chelsea in the Premier League so far this season.
Sarri insists Chelsea will look to rotate their league line-ups come the Christmas fixture glut though, and maintains he is handing players opportunities to impress in cup competitions.
‘If you look only at the Premier League, the situation is bad, you’re right,’ said Sarri.
‘But we’ve used 26 players in all competitions this season. I have to look at all the competitions, because 90 minutes is 90 minutes.
‘I think the rotation overall is good at the moment.
‘Of course if you look to December, January, you’ll need to change also for the Premier League, because there will be matches every three days.
‘So we’ll need to change there too, of course.’
