Juliano Belletti feels Barcelona star Neymar is unlikely to leave Camp Nou but acknowledged anything is possible amid rumours of interest from Manchester United.
The Brazil captain was linked with a switch to Old Trafford last week although both Barca boss Luis Enrique and United counterpart Louis van Gaal refused to comment on the reports.
When asked over whether a United move was likely to appeal, he told Omnisport: "No I don't think so, Neymar is very happy in Barcelona.
"He has adapted to the team, the city and his family have adapted as well but nothing is impossible."
On what the groups could offer his former sides, the one-time European champion added: "It depends on the team.
"Barca and Chelsea are always favourites but that's the Champions League, it's about pressure and for sure they're prepared for any difficulties."
