Chelsea fans have been monitoring the happenings at Old Trafford especially with two players they lost this transfer window to the Red Devils.
Nemanja Matic was sold to Man United and Chelsea also lost the battle to secure the services of Romelu Lukaku after Jose Mourinho stole the show on the Blues late on to snatch the striker.
Chelsea were pushed to then go unrivaled for Alvaro Morata from Real Madrid, a player Mourinho had shown interest in earlier in the summer to no avail. It was said afterwards that Man United had had the better deal of the two, with Lukaku a more natural goalscorer than Morata who was yet to acclimatize with his new environment.
However, almost halfway into the season, Chelsea fans would feel the right to have a go at their former striker who snubbed them for Old Trafford.
After another poor performance in the Premier League against a top six side, Lukaku was at the receiving end of some backlash from Chelsea fans.
