Jose Mourinho was appointed Roma manager on Tuesday, but Spurs still have to pay him £10million.
Mourinho landed a new job just 15 days after being sacked by Tottenham.
The Special One signed a three years deal with the Italian side worth £5m a year — compared to the annual £15m he was getting at Spurs.
But as part of his severance, the North Londoners agreed to pay him the shortfall in salary if he took another post on lower wages before the end of his contract next summer.
That means when Mourinho takes over at the Stadio Olimpico this summer he will receive £5m from Roma and for next season, he gets £10m from Tottenham.
But Spurs have saved £5m on what they would have paid him had he not accepted another job.
The ex-Chelsea, Inter, Real Madrid and Manchester United boss is keen to show he is not at fault nor been affected by his shock departure after just 17 months in charge.
Mourinho, 58, will replace fellow Portuguese Paulo Fonseca.
He said: “The incredible passion of the Roma fans convinced me to accept the job and I cannot wait to start next season.”
