Mourinho has been out of work since December, but is widely expected to return to management.
Former Chelsea manager Jose Mourinho has said he will return to management next season and sign a contract by June 30th, though he didn't say where, but admitted that being appointed late means pre-season isn't going to be the easiest of experiences, according to the Associated Press.
Mourinho - who has sacked midway through this season after a poor defence of the Premier League title - has been strongly linked with succeeding Louis van Gaal at Manchester United, with the Dutchman's future a source of constant speculation all season.
He said: "It's difficult because when you get a new club in this period normally the clubs they did already their work. I give you an example. I'm not the Chelsea manager but I organized the Chelsea pre-season in many aspects because I did that 10 months ago.
"Clubs have their commercial, marketing departments always involved in everything. When a new manager arrives in May, June it's very difficult to touch in some points but we know that."
Speculation about Mourinho to Old Trafford continues to rumble on, but it may become clearer after United's final two games of the season, where they have to beat Bournemouth to have any chance of qualifying for the Champions League and an FA Cup final against Crystal Palace the following weekend.
On that particular subject, Mourinho added: "I don't know. I know nothing about it really."
It seems to be a case of watch this space, but if he is a late appointment and pre-season isn't exactly how he would like it, it may not be unfair to expect a slow start to the season from whichever side Mourinho manages, and as he tries to implement his ideas.
His future, especially with the focus on Manchester United, has become something of a saga and no doubt Mourinho wants it solved relatively quickly, and United fans want a bit more clarity of the direction they are going in under whichever manager they choose.
