Barcelona defender Martin Montoya has warned Neymar that Lionel Messi is still the main man at Barcelona ahead of the Brazilian's transfer to the club.

The Santos forward will move to the Liga champions next season after the deal was officially announced last week.

However, despite Neymar being one of the hottest commodities in world football, Montoya has told the forward that Messi will always be the biggest name at Camp Nou.

"He's a star and he is really going to entertain. It's going to be incredible," Montoya told reporters.

"[However,] Messi is the main captain. Neymar has to adapt to the team and especially to Messi. If Neymar behaves, he'll get along with Messi. Leo gets on well with everyone.

"Will he struggle to get along with Messi? Those are things that they're saying in the Press. Leo is a great person."

Neymar has signed a five-year deal at Camp Nou, with the fee believed to be in the region of £24m.
