Jose Mourinho's relationship with Ashley Cole has become complicated, according to The Daily Mail.
Reports have suggested that Cole's smoking habit has caused issues with the Blues boss throughout the campaign. The 'Special One' is completely against smoking, but has been unable to convince the former England international to give up the habit.
Cole endured a frustrating season at Chelsea, having lost his place in the side to Cesar Azpilicueta before the turn of the year.
And, despite starring towards the end of the season, it now appears that the Chelsea man will depart Stamford Bridge in the up coming market.
It appears that Cole's smoking habit - combined with a number of other factors - have consequently led to his downfall at the Premier League giants.
Mourinho and his Chelsea side will now hope to progress in 2014/15, but it's unlikely Cole will play any part in the future of the club.
