Manchester United fans were delighted to see new signing Nemanja Matic training alongside his Red Devils teammates on Tuesday.
And were over the moon to see he has already made friends, or rather, has reacquainted himself with Juan Mata, who he very briefly played with at Chelsea.
The pictures showed the pair chatting away in the Manchester rain while assisting each other during stretches - all of which we'd imagine is painful viewing for Blues fans.
Matic put pen to paper on a three-year deal with the Old Trafford club after completing a £40million transfer from Stamford Bridge.
He trained at Carrington for the first time on Tuesday, after revealing Jose Mourinho, who he also knows from his time at Chelsea, played a big part in his decision to sign.
"I am delighted to have joined Manchester United. To work with Jose Mourinho once again was an opportunity I couldn’t turn down," explained Matic.
"I have enjoyed my time at Chelsea and would like to thank the club and the fans for their support. I cannot wait to meet my new team-mates and to start training with them.
"This is a very exciting time for the club and I am looking forward to playing my part in creating more history for this great club."
After beaming from ear to ear at the pictures, Man United fans took to Twitter to voice their excitement ahead of the new season.
And, of course, poke fun at Chelsea supporters witnessing a Blues reunion at Man United.
