Manchester United misfit Bebe insists he is unaffected by speculation linking him with a move to Portuguese giants Benfica this summer.

In one of the most bizarre transfers of the Sir Alex Ferguson era, United paid £7.4m to sign the unknown Portuguese forward in 2010. A couple of dismal performances for the club followed by a succession of failed loan spells saw him slip off the radar but an impressive stint with Pacos de Ferreira has seen him thrust back under the spotlight.

The forward has netted six goals in his last seven games for the Portuguese Liga side, including a sensational solo effort against Arouca last month.

His rise in Portugal has seen him linked with a summer move to league leaders Benfica, but Bebe insists he is solely focused on his side's end of season run-in.

"The rumours about Benfica and other clubs do not affect me. I still have the desire to do my best for Pacos de Ferreira," Bebe said told Portuguese channel TV Sport.

"At the end of the season I will talk to my agent and decide what is best for me."

Bebe made just seven appearances for United before he was shipped out on loan first to Besiktas and then Rio Ave. Both loan spells were ravaged by injury but this season he has begun to piece his career back together, scoring nine goals for Pacos.

With the club sat second from bottom of the Portuguese top flight, another spell at the club next season is unlikely.

And with sweeping changes expected at United this summer, Bebe's future at Old Trafford remains uncertain. But the forward, whose performances have impressed Portugal national team boss Paulo Bento ahead of the World Cup, still wants to return to his club and be given the chances he believes his performances on loan have merited.

"I still hope to return to Manchester United, but nobody from the club has spoken to me," Bebe said in March.
