Former Chelsea chief executive Peter Kenyon would not think twice about bringing Jose Mourinho back to the club if he was still at Stamford Bridge.
"If I was at another club and looking for someone who would give me the maximum chance of winning, it's Jose Mourinho," Kenyon told BBC Radio 5 Live's Sportsweek programme.
"You've got one of the best clubs, one of the best owners and one of the best coaches - it's a hard combination to resist.
"I'd need some other very strong candidates to look elsewhere and you'd have to say he's very much on the shortlist.
"Pep Guardiola would have been up there (as a candidate) but he's not available. (Malaga coach) Manuel Pellegrini you would definitely look at. But if I was looking at Pellegrini or Jose, Jose would win hands down."
Mourinho is currently coach of Real Madrid but has dropped several hints he may leave the Bernabeu at the end of the season and could be open to a move back to the Blues.
It was Mourinho's much-publicised falling-out with Chelsea owner Roman Abramovich which led to his departure in September 2007, but Kenyon thinks the Portuguese may give into the lure of working at Stamford Bridge once more.
However, Kenyon warned that Mourinho and Abramovich will have to sit down and sort out their problems before there is any possibility of a Stamford Bridge reunion.
"They're both very strong individuals and before this appointment happens, if it happens, there will be an awful lot of discussion between those two," he said. "It's a very different team now, that is at a very different part of its evolution as a major European team, and clarification is needed over players."
