The Chelsea defender hasn't always been everyone's cup of tea, with his occasional lapses in concentration often proving costly, but there were no such problems on Sunday in a fine display. I think that, later in the evening, I will see the doctor for the first results, but I think the real result will only be known tomorrow.
"We were in good control of the match". Yesterday in 10 minutes we had three injuries - Fabregas, Loftus and Drinkwater - then Giroud today, and we were already without Pedro and Odoi.

Chelsea held onto the lead given to them by N'Golo Kante's earlier strike to move five points clear of fifth-placed Arsenal.
"I am happy with the team because we dominated for 85 minutes, although we didn't kill the match, so we had to fight again for the last five minutes", Sarri told BBC's MOTD.
Reflecting further on the game, he added: "They were very good, but in the first half our discipline was very focussed and we limited their goalscoring chances, and apart from their offside goal I thought we did quite well".
Kante broke the deadlock in the 51st minute when his darting run into the Palace penalty area was spotted by defender David Luiz who fed the France World Cup victor to score from close range.
Still, there appears the added competition from AC Milan, although the Italian side's Financial Fair Play concerns may mean that the Blues could take advantage over the proceedings by discussing a straight-cash deal rather than going with monthly settlements.
"We could have scored early but they also did a great match defensively, which is why it was so hard", Chelsea's Luiz told reporters.
