There are a lot of thoughts circling at Chelsea at the moment, predominantly after their defeat to Steaua last night, being 'Can Rafa go now?'.
When it comes to the manager they want in, one man stands truly head and shoulders above all others - Jose Mourinho.
The Special One has had a topsy turvy season at Real Madrid, having effectively lost their title to Barcelona by December and falling out with big names like Iker Casillas.
It has all prompted speculation he is to leave the club in the summer, and don't expect the win over Manchester United to change anything.
While it could conversely been considered that a loss would have been the last straw for the Madrid hierarchy, Mourinho is on course to achieve the one thing he would really love.
Mourinho would find nothing better than winning the Champions League and walking away, just as he did at Porto and then Inter Milan, giving Madrid's board a two-fingered salute in the process.
But if Chelsea think he is going to come running straight into the cash-laden arms of Roman Abramovich they might want to think again, because the manager is playing his cards close to his chest.
Chelsea are clearly a consideration for him, but likewise it is obvious he would relish the challenge of managing Manchester United.
Replacing Sir Alex Ferguson will be seen as the biggest challenge in football, and once he goes back to Chelsea, surely it will be impossible for him to jump ship to Old Trafford.
So Mourinho has a decision to make. The problem is Sir Alex doesn't look like going anywhere. 'How could I walk away from nights like this?' he asked in the prelude to kick-off on Tuesday.
The loss and the manner of it will surely only intensify his desire to continue and attempt to win a third Champions League trophy, so if Mourinho wants the Old Trafford hotseat he may have to wait a while.
The signs are there that he is keeping his options open. Any new manager will need the blessing of Sir Alex, and the two are on great terms. Mourinho was keen to be respectful in both legs towards United, a trait unusual for him - Compare his antics against Manchester City for example.
He was deliberate not to antagonise the Old Trafford crowd in anyway, a far cry from his touchline run back in 2003 with Porto.
Chelsea will be confident in that they can offer him an escape route from Madrid right now, which United can't. But the further complication could be PSG.
Manager Carlo Ancelotti has not signed a new deal which expires this summer, and Mourinho is the name which will give PSG the global authority and high profile their new challenge really dreams of.
For Jose the job will be a stop-gap until United, a chance to win the league in yet another country, his fifth, and a squad and finances capable of competing for the Champions League.
Certainly his appointment at Chelsea is no given, and this has to be a worrying thought for fans of the Blues who are so desperate to see him 'come home'.
Where will Mourinho manage next?
