Walker, who has played alongside Dele for Spurs and England, tried to talk the match officials out of their dismissal decision - despite being on the opposing side. He has told The Kyle Walker Podcast of that surprising behaviour: “I think my heart kicked in. Anyone else, I would have just let him get sent off. Especially a man down at the San Siro, you think, okay, we go and do what we've got to do.
“I know what he's tried to do. We've all done it where you just clip the ankles of someone and they don't get the counter attack. But maybe where he's not played for a couple of years and is out of the rhythm of the game and everything like that, he's caught Ruben a little bit too high. And that was it.
“Of course, I think in footballing terms, we need ten men. We want the ten men, AC Milan want the ten men. But for the personal relationship that I have with Dele, for the number of years that I've known Dele, for what he's been through - which obviously he's publicly said and I think he's been very strong and open about that and very brave in coming out and saying what he said - to finally come back after such a long time of being out, to then get sent off for a not really cynical challenge. I think your heart just kicks in, as I said at the start.”
