It looks like Sergio Busquets will stop playing football and will enjoy his old age to rest or maybe also do business again as a football coach even though he is still not too old to be a soccer coach, but if he until now still hasn't shown where he will go because Sergio Busquets is still too in love with Barcelona. But usually those who are not extended at Barcelona will be targeted by other clubs, so it depends on whether Sergio Busquets wants to continue his football career or not.
Busquets is likely to leave Barcelona in the summer and continue his career in MLS. He said that it was important for him to play in the main team and I think that the amount of the contract is take not the last place in this choice. Many star players continue their careers in the MLS. Busquets has had a great career at Barcelona, he's been with the team since 2008 and I think of players like that that they should finish their career at the club where they spent their best time.
And yes, I have to constantly use one of these clarifications because for the top teams, the group stage is essentially a formality or a way to try out their own strengths/new tactics. Results in most groups are a foregone conclusion.
