The Wigan Athletic winger has emerged, according to the Birmingham Mail, as a top target for West Bromwich Albion.
Mackay, though, is quickly growing accustomed to speculation surrounding his star turns.
He has seen Shaun Maloney generate interest during the January window, but is backing McManaman to follow the Scot’s lead and shrug off the speculation until there is a decision to be made.
Mackay told the Wigan Evening Post: “I hope Callum would deal with the situation the same as Shaun has.
“I’ve only known him for a few weeks but he seems a really nice young lad, well grounded. This is the first time he’s found himself in this kind of situation, but I do think he’ll handle it in the right way.
“He’ll be disappointed that he’s been forced to miss the last three matches through suspension. He’ll want to prove a point to himself when he does get back on the field.”
McManaman has graced the top-flight before and will be as disappointed as anybody to find Wigan struggling in the second tier.
He is, however, committed to a long-term contract at the DW Stadium and must continue to give his all to the Latics cause until told otherwise.
Wigan have no need to sell and any decision on winter sales will be taken by the club’s management and board, with it important for players to be kept away from the spotlight as they endeavour to bridge the five-point gap which currently separates them from safety.
