Jose Mourinho will only make the move to Chelsea if Roman Abramovich is no longer in charge of the club, according to numerous sources, with the Blues manager believed to be considering other options in the Premier League as the summer draws near.

Mourinho has been connected with a host of top English clubs as he comes under increased pressure at Real Madrid, despite keeping the Spanish giants at the top of the La Liga table and looking a serious threat in the Champions League.

Manchester United have often been touted as a possible destination for the Portuguese tactician in the future, with Sir Alex Ferguson admitting he may only have three years left before he decides to retire.

And the Tottenham post may well be open if Harry Redknapp becomes England manager in the summer, leaving a side that will possibly be in the Champions League open to a new manager for the next season.

And though news outlets such as the Sun claimed that Mourinho had told close sources that he would consider a move to Chelsea if the offer was right, the former Blues manager has reportedly told friends he would only take the position if Roman Abramovich stepped down as owner.

"As long as Roman leads the club, Mourinho will not go," the source said, as reported by Le 10 Sport.

The Telegraph also reported today that a move for Cristiano Ronaldo could be on the cards for Chelsea as well, which would no doubt be boosted by Mourinho's move from Madrid to the west London club.

Abramovich and Mourinho have a very volatile relationship, and though reports have suggested they patched up their differences after their acrimonious end in 2008, it doesn't appear that they've come to an agreement as the Russian looks for yet another manager to have a shot at Stamford Bridge.

Without a permanent manager, Chelsea have been performing well, with Roberto di Matteo taking the club to four wins, a loss and a draw since Andre Villas-Boas was sacked.

And with the side looking to challenge for a Champions League trophy this season, after showing heart against Napoli to win 4-1 in the second leg of the final 16, top-tier European football could still be on the cards for the club that currently sit five points outside the top four in the Premier League table.
