Celtic hero Scott McDonald believes Kieran Tierney should turn down Everton.
McDonald reckons the Hoops left-back could earn a move to Manchester United if he waits a year.
He told BBC Scotland: "I think he might possibly just stay on for even another year, maybe two more.
“If they're offering the amounts of money that can be offered down in England then it would be a huge temptation but we've seen in the past how much he loves the football club and he's still only young.
“If he holds out another year or two, I think opportunities do open up. Someone like Man United, that has been touted with the struggles that they have found at left-back.
“Certainly, if they were the ones tabling the bid, you would jump. I think you would have to jump to go to a Manchester United or the likes of them in the Champions League competitions. Everton, outside the top six clubs, you would argue are probably the next one."
