Having suffered exits from the Champions League and FA Cup respectively, Spurs have been left to try to close down Chelsea, who sit seven points ahead of them in fourth position.
Although high-profile additions were made in January, Mourinho will prioritise strengthening his defence during the next transfer window.
With that in mind, Sports Mole assesses how Spurs may line up at the beginning of the next campaign, whenever that may be.
However, expect a new arrival at right-back, potentially in the form of Norwich City's Max Aarons who has been frequently linked with a switch to North London.
Much of the midfield and attack is expected to remain the same, providing that Mourinho does not look to cash in on Tanguy Ndombele after just one season.
Son Heung-min and Harry Kane are certain starters once they have returned from their respective injuries, with Steven Bergwijn occupying a role on the right wing and Dele Alli continuing in somewhat of a free role behind the main frontman.
