Zlatan Ibrahimovic is "a world-class player" and "world class-person", according to his Swedish international teammate John Guidetti.
Following weeks of speculation, Ibrahimovic is expected to reveal his next move on Tuesday afternoon, with the 34-year-old widely tipped to head to Manchester United.
Celta Vigo striker Guidetti, who has previously represented Manchester City, has backed Ibrahimovic to thrive in the Premier League.
"I think he knows the Manchester weather like I do. He will settle - anywhere he has gone, he has performed," Guidetti told reporters.
"He is a world-class player and is a world-class person. Any team that gets him should be very grateful. He is fantastic - the way he speaks with the younger players, the way he demands quality. It is a true pleasure to play with him.
"There'll never be another Zlatan - he's a one-off. The way he talked and behaved has inspired me."
It is understood that Ibrahimovic will sign an initial one-year contract at Old Trafford.
