Jose Mourinho says Antonio Conte's Chelsea side will not be leading the Premier League table this season if he had led the Blues to European football.
The current Manchester United coach was sacked last season by Chelsea after seeing his side closer to the relegation places.
The Portuguese has now claimed that his failure to achieve European football for the Blues means they have less matches which has help them rise to the top of the table.
Speakng ahead of the FA Cup clash between Manchester United and Chelsea on Monday, March 13, Mourinho blamed the Chelsea player he worked with for theur inability to achieve European football.
"The most difficult thing to have is the time to work [on the training pitch] and they have time to work," Mourinho said.
"I know that he [Conte] said a couple of weeks ago that it's not his fault that they are not in the European competitions - it's my fault and the players' fault.
"But the reality is that he got a situation in his hands where they have time to work, time to rest, time to relax, time to disconnect, time to travel, time to have holidays, time to go and enjoy America for a couple of days, they have time for all of these things, so they are in a position of privilege, the same privilege that Liverpool had a couple of years ago when they almost won the Premier League.
"But I don't want to say that they don't deserve credit for it. I know what I did at Chelsea but I am the kind of guy that when I move I have no regrets and I am not looking for bad feelings at all."
Mourinho's Manchester United travel to Stamford Bridge on Monday for an FA Cup quarter-final clash against his former club.
Mourinho's side side are still competing in the Europa League as well as the Premier League and the FA Cup.
