The agent of Benfica midfielder Nicolas Gaitan has confirmed the interest of bigger clubs.

The Argentine is admired by Manchester United boss Sir Alex Ferguson, while PSG are also keeping tabs on his form.

"I know there are great clubs observing Gaitan but, to this date, no-one has contacted me to express that interest in an official way," Jose Iribarren told Record.

"I think this is a natural situation, as Gaitan is playing in the Champions League and has returned to the Argentina national team.

"It is normal there are more interested clubs in his services."
