Both Man United and Chelsea registered crucial wins in their weekend fixtures against Watford and Norwich City respectively. Man United were on the verge of securing yet another draw but a late winner by Bastian Schweinsteiger was all the Old Trafford side needed to earn three crucial points away at the Vicarage Road Stadium.
In the other match of the day, the inconsistent Diego Costa scored Chelsea’s goal against the Tractor Boys to hand Jose Mourinho the much-needed relief after losing three consecutive league matches. However, things were not so rosy for the Gunners who suffered a shocking 2-1 defeat away to The Baggies. After the defeat, a section of Man United and Chelsea fans teamed up together on Twitter to roast their rivals, Arsenal.
Here are some of the top tweets
