The arrival of Philippe Coutinho could transform Gyfli Sigurdsson as a player at Everton, according to Noel Whelan.
The former Leeds United striker, speaking exclusively to Football Insider, insisted the former Liverpool playmaker would bring the best out of his teammates.
As reported by the Sun, Everton are confident about striking a deal to sign the 28-year-old from Barcelona this summer.
It is said a £35million deal has been agreed in principle, although the move hangs on Coutinho proving his fitness.
The Brazil international has suffered with knee problems all season and underwent surgery at the start of April.
Whelan admitted Coutinho’s arrival could force Carlo Ancelotti into a shakeup of his current attacking midfield options.
However, he suggested the Barcelona man’s quality could help Sigurdsson transform in a deeper role.
“You think about Gylfi Sigurdsson, he could probably play in a central midfield area anyway,” Whelan told Football Insider’s Russell Edge.
“He’s got the experience and discipline to play there. He has done exceptionally well, you can see the change in him since Ancelotti’s come in.
“He has taken the captain’s armband and been given that trust. The performances he has put in have been excellent.
“I think a player like Gylfi Sigurdsson can play in behind Coutinho. You’re going to get the best out of players.
“He definitely can play that role and when you get a little bit older, sometimes it suits your game a little bit more.”
Sigurdsson has been used in a variety of midfield roles this term, including a left-winger.
He has scored eight goals and contributed nine assists in 39 appearances for Everton this season.
Meanwhile, Coutinho has only played 14 times for Barcelona this term due to injury.
