Looks like a goodbye.
He did it also after scoring VS PSG, with a tribute to the kop and a nostalgic look last summer, tho it didn't ended with a transfer, so I keep an hope :D
But I pray that he will leave for City if he does leave, he's an awesome player and human being. He deserve the best. I see the perfect match with Pep.
Take care of him <3
You'll be a bit dissapointed defensivly ifd he play as a RB, but trust me, if he play CDM, he can become really quickly one of the most loved player of your squad. He's complete, regular, NEVER injured (50/55 match / years), give it all on the pitch, and a really quiet and hard-worker guy.
