Rubin Kazan have attempted to warn Liverpool off signing Yann M'Vila by claiming the France international is unable to reproduce his best form because he suffers from homesickness.
M'Vila has constantly been linked with moves to the Premier League but joined Rubin from Rennes in January 2013 however a change of manager has compromised the 23 year old's career in Russia.
And Rubin boss Ribat Bilyaletdinov says that with M'Vila having performed as if he has already joined Liverpool a deal to take him to Anfield is someway off.
"He has to prove his value and work like everyone else. I don't mean that he doesn't work, but we can see that he misses France," Bilyaletdinov told France Football.
"In January M'Vila behaved badly - one day he trained, one day he didn't. Maybe his agents had promised him something. He thought he was already in Liverpool.
"I told him: 'It is not your level. If you go, you will be on the bench'. He was very disappointed.
"Now I haven't seen him for a while. I have been told he is in France to cure an injury. Even if he is back to full fitness, I don't know where to play him."
M'Vila was pictured watching the Merseyside derby between Everton and Liverpool earlier in the season though has previously been linked with north London duo Arsenal and Tottenham Hotspur.
Regardless of whether Liverpool are successful in their pursuit of the Premier League title, manager Brendan Rodgers is expected to look to improve his squad in the summer transfer window ahead of the expected return of the Champions League to Anfield.
Liverpool have an 11-point lead over fifth place Everton with the Toffees having six games remaining, meaning eight more points will guarentee a top four finish this season, and dramatically improve The Reds' ability to attract world class players to the club.
