Chelsea fans got more than they bargained for on Sunday afternoon, as three very special guests were in attendance at Stamford Bridge.
As Antonio Conte's side prepared for their Premier League clash against West Brom, looking to return back to the top of the league after Arsenal's victory on Saturday, eagle-eyed supporters spotted Andrea Pirlo, Joe Cole and Frank Lampard in the stands.
The Italian midfielder was invited as a guest of the club, while Joe Cole has been training with the club in order to keep fit during the MLS winter break. Lampard was joined by his wife while taking in the action.
Naturally, fans were excited to see the prestigious trio in the stands, so Goal takes a look at some of the best reactions on Twitter.

And, while it was Lampard and Cole who enjoyed years of success at Chelsea, it was a very sharply-dressed Pirlo which had the home fans purring.
