Chelsea owner Roman Abramovich has reportedly visited the Blues' Cobham training ground this week to grill the players and coaching staff following their draw with Juventus in the Champions League on Wednesday.
The European title holders slipped from a 2-0 lead to draw 2-2 with the Serie A champions at Stamford Bridge, which is believed to have frustrated the club's billionaire owner.
It is understood that the Russian businessman turned up at the training ground unannounced to speak to the players and manager Roberto Di Matteo on the training field the morning after their draw, according to the Daily Mail.
Meanwhile, Chelsea midfielder John Obi Mikel has closed down his Twitter account after receiving alleged racial abuse on the social network site.
