Jose Mourinho will be paid £15m next season as Roma manager, but Tottenham Hotspur will have to pay £10m of that money, the UK Sun reports.
The 58-year-old was sacked at Spurs last month and has quickly landed himself a new job in Serie A.
Mourinho has signed a three-year deal with Roma, but the first of those three years will be much more lucrative than the next two.
With a year left on his deal in north London when he was dismissed, his contract stated that Tottenham will pay out his deal if he did not get a new job, or make up the shortfall if his new club was paying him less.
Roma agreed a deal to pay Mourinho £5m-per-year, meaning Spurs will have to shell out £10m for him to manage another club.
The fact Mourinho has taken a new job actually saves Spurs some cash, as they would have been paying him the full £15m next season, if he had not been given more work.
