Brentford have extended Chris Long's loan spell from Everton until the end of the season.
A knee injury and excellent form of others meant the 26-year-old has struggled to break in to the first team at the Nou Camp.
Afellay has made just eight league starts since signing from PSV Eindhoven for £2million in December 2010, leading to the player being linked with Arsenal and Inter.
"People should not take all these rumours about an imminent transfer too serious," agent Rob Jansen told Voetbal International.
"Leaving Barcelona is not an option at this point. Ibrahim is feeling very well at Barca and is getting playing time.
"It's true that there's plenty of interest, but that's always been the case. There's absolutely no reason for him to leave the club.
"Can we completely rule out a summer exit? You never know in football, but it's highly unlikely that he will leave Barcelona."
