Walker-Peters’ move to Southampton was seemingly made possible due to Pierre-Emile Hojbjerg’s switch in the opposite direction, with the midfielder impressing since joining Spurs.
However, Walker-Peters has proven at Southampton this season – and against Tottenham – that he would have at the very least been a strong option for Mourinho.
There was more impetus from Tottenham in the second half as Gareth Bale brought Spurs level with a smart finish inside the box.
Son thought he had scored Tottenham’s second with 15 minutes remaining, only for VAR to rule it out for offside.
But the South Korea international did eventually bag his goal and the winner for Tottenham late on when Moussa Djenepo conceded a penalty.
It may well be a crucial three points for Tottenham in their fight to clinch a top-four spot, but there will still be some concerns on a few areas until the end of the season.
