Maurizio Sarri questioned the attitude of his Chelsea players and accused some of over-confidence after they suffered a chastening 2-1 defeat at Wolves that leaves them 10 points behind Manchester City, the Premier League leaders, before Saturday's meeting between the two clubs at Stamford Bridge.
Marcos Alonso has urged Chelsea to forget about the growing gap to Manchester City, with the Blues' title hopes hanging by a thread.
On the other hand, Wolverhampton Wanders are now 12th on the Premier League table and they ended their run of six straight Premier League defeats by winning against the Blues.

Rojo forced Leno into a fine save but it was Arsenal who led again in the 68th minute when Alexandre Lacazette got the final touch but the advantage lasted less than a minute as Arsenal's defence allowed Jesse Lingard to steal in and slide a shot under Leno.
And all of Loftus-Cheek's league matches this season have been off the bench, with his only starts coming in cup competitions. We had to play 30, 35 minutes. We all know. I've trained with him for five years, I saw him when he was young, now he is not so young but he can still improve.
Xherdan Shaqiri finished off a rapid counter-attack in Liverpool's 3-1 win overBurnley at Turf Moor, while James Milner also scored with a pinpoint finish into the bottom corner.

The Blues had taken an early lead through a deflected Ruben Loftus-Cheek effort but Wolves produced a spirited second half display and turned the game around with goals from Jimenez and Diogo Jota. After the first goal, the 1-1, having been in full control of the match, we were suddenly another team.
