Do Chelsea need 'more emotional control'?

With Chelsea currently having the most yellow cards in the Premier League, it could suggest a discipline issue that they need to look at. You do not want that hanging over you where you get a perception of the squad that they are ill-disciplined – particularly around the media and with officiating.

They are a young squad, but I do also think some of the refereeing has been really inconsistent this season. Some yellow cards and some red cards throughout this campaign, in one game it is a yellow card but in another game it is not. In one cup game it is a red but then in other games it is a yellow.

Refereeing, at the end of the day, it is an opinion, it is not all based on facts. We see there are some referees that would allow small stuff to go, and then there are some referees that like to nip it in the bud straight away and get their card out, which sets the tone right from the beginning.

It is difficult because at the end of the season, to have it on record as the worst discipline in terms of yellow cards is not something the club will want. It could be an issue with them being such a young squad, but it is not like Chelsea are always up there for yellow cards. After this season, it might be something they have to look at with these players, bringing that little bit more emotional control at times with these bookings.

Looking at Nicolas Jackson's red card in particular against Newcastle, it could prove to be costly with two games remaining when you are fighting for that Champions League spot. Newcastle now creep away from them that little bit more with the points on board.

While I don't think it was reckless and I felt the referee got it right at the time, it was a naughty challenge. It comes down to those inconsistencies in decisions and it was hugely costly for Chelsea.
