Chelsea boss Enzo Maresca faces an anxious wait on injury news as his Blues stars return from international duty next week.
Maresca's charges signed off for the November international break with a battling 1-1 Premier League draw against Arsenal as they moved up to third in the EPL table.
However, ahead of their return to action at former club Leicester City on November 23, the Italian coach will make checks on the fitness of some key players.

Romeo Lavia was forced off after 68 minutes in the draw with Arsenal, ahead of joining up with Belgium for their two UEFA Nations League games, against Italy and Israel.
Lavia indicated before the clash with Italy he would be fit enough to feature in Brussels but he was later ruled out by head coach Domenico Tedesco.
Tedesco confirmed the 20-year-old was not pain free ahead of their 1-0 loss to Luciano Spalletti's team and he is also expected to miss out against Israel on November 17.
"Romeo Lavia had a hamstring problem, it was bothering him ahead of the Italy game, so we didn't want to risk him", he said.
"It’s not like they’re trying to escape. Players really have injuries. I’ve never had to deal with this kind of situation before."
Lavia is expected to head back to London for tests on the injury with Maresca awaiting an update before confirming his squad to face the Foxes.
Alongside the mixed update on Lavia, Maresca will be boosted by a non-injury related early return for Pedro Neto, who has been released from Portugal duty.
Roberto Martinez confirmed his call to send four players back to their clubs - including Neto - after securing a spot in the Nations League quarterfinals with the former Belgium boss looking to test new players against Croatia on November 18.
