- Coutinho's loan stint with Bayern will expire this summer.
- Sylvinho believes the Brazilian can make a difference when he returns to Camp Nou.
- He also tipped him to thrive elswhere if he does depart.
Sylvinho revealed during an interview with Ser Catalunya: "He has a lot of quality, he has a goal, but it didn't work out for Barca.
"Hopefully, if he returns to Barcelona he can triumph, if not at Barca he will triumph in some other great club."
Coutinho's future remains a subject of speculation heading into the summer transfer window.
The Brazilian's loan deal expires at the end of the current campaign and Bayern appear unwilling to sign him permanently.
He would either return to Camp Nou and represent Barca for the upcoming campaign or seek a move away from the club.
