Lukaku now needs to do his talking on the pitch - an apology from him will mean nothing at all.
If he and Tucbel have come to peace, then that's great for squad harmony, however we should seriously look to move on from Lukaku. A few poor performances from him will lead to match-going fans getting on his back and how long before the next interview?
I think he'll play vs Spurs, purely to give Kai a rest, however I wouldn't put him straight back in as first choice.
