Tottenham Hotspur manager Jose Mourinho mocked England boss Gareth Southgate by calling him "Gary" as the row over managing Harry Kane's workload escalated. Mourinho was responding to Southgate's comments about Kane's game time by saying he will not play the striker in any of the football club's friendlies while also questioning the national team's plans for his player. With fixtures coming thick and fast for Spurs, Mourinho had called on Southgate to protect Kane by not playing him in all of England's upcoming games, including a friendly with Wales and Nations League matches against Belgium and Denmark this month. After a gruelling run of fixtures for Tottenham, which continued with a 7-2 win over Maccabi Haifa in the Europa League on Thursday, Mourinho fears Kane could be in danger of burnout. Southgate recently said Mourinho must look after Kane in April and May with the European Championships around the corner. Kane scored a hat-trick to guide the north London club into the Europa League group stage with a hat-trick in the win over Maccabi Haifa - their third game in five days. "This match was a fundamental match for us. A match that means a few million pounds and means that we are in a group phase of a competition that we have ambitions," Mourinho said. "For my friend Gary, I can promise that until the end of the season I don't play Harry Kane one minute of any friendly match." Spurs face Manchester United in the Premier League on Sunday.
