what rest will he get ? does he stop training and go on holiday, or is he just rested on match days ?
if we had signed a few players maybe we could have rested Kane for a few more weeks and then allowed different players 2 weeks off at different times in the season
Let him train to keep up match sharpness but for easy fixtures he should be rested, like the Watford match before a difficult Inter away game.
Although not signing any players isn't ideal players like Son, Lucas and Alli can play striker to rest Kane.
