The Ivorian, with the home side hanging on by their fingernails in the wake of a late Celta goal, lost his cool with Manchester City reject John Guidetti during a heated exchange and received his marching orders after pushing the Swede in the face.
That was his second red card of the season, adding to the one picked up against Saint Etienne, and it means he will miss the final in Stockholm.
And Mourinho, speaking after the game, admitted he didn’t see the incident but labelled the 22-year-old, a rock at the back up to that point, as naive.
“I didn’t see the incident but he was phenomenal,” he said.
“The game was emotional for everyone. Roncaglia isn’t new, Bailly was naive. We’ve lost a very important player for the final and we don’t have many.”
Guidetti must have said something incredibly provocative to coax Bailly – and indeed Antonio Valencia – into lunging out at him like that, with nothing seemingly going on until the Celta forward, who later missed an open goal, ended up on the floor, exaggerating the severity of his blow to his heart’s content. The Ivorian actually made another attempt to go after him after that, only for his teammates to calm him down.
The details, I’m sure, will come clear in due course. What can be said for certain is that Mourinho will be without his best centre back of the season for the Europa League final against Ajax on May 24. Phil Jones and Chris Smalling are both now available, but neither bring that same kind of imperturbable solidity Bailly would have promised in Stockholm.
A massive miss, that’s for sure; supporters will just hope it isn’t a decisive miss.
