FC Barcelona star Neymar believes that his Argentine teammate Lionel Messi will stay on with the club after they secured an improbable come-from-behind win in the Champions League round of 16 tie here on Wednesday.Barca completed a 6-5 aggregate win against Paris Saint-Germain after suffering a 0-4 hammering in the first leg in Paris."Messi will renew, for sure," Neymar was quoted as saying by ESPNFC after the match.The Brazilian star scored twice as Barcelona became the first side to ever turn around a four-goal deficit in the Champions League."We had the game lost in Paris and here we played with responsibility, with joy, with pressure and with the ball," Neymar said."The first week after Paris was tough, it did a lot of damage, but then we recovered our football and since the second week we've been desperately waiting for the game to arrive and to write history."
