Celtic are investing heavily in the transfer market again this winter as Ange Postecoglou tightens his grip on Scottish football.
The addition of Oh takes his total of new signings to four and his spending up to almost £8m.
The club could not be in a healthier financial state and that is because we are not only prudent when we buy, but also when we sell.
Sell on clauses bring in extra millions to the club and Barry Ferguson reckons that this summer, we could be about to be quids in again as he predicts Kieran Tierney to move from Arsenal to Manchester.
Speaking on The Go Radio Football Show, Ferguson said, “He is too good to be on the bench. He is too good. Plain and simple.
“And I don’t think he’ll be happy. He strikes me as the type of guy who wants to play.
“He’s good enough to play.
“If he doesn’t play in the next few months, I don’t think he’ll be going in this window, I think the next three months will be key if Kieran Tierney is going to stay at Arsenal.
“And if he’s not going to play, then I think he will ask to go. And don’t be surprised if Man City or Man United is going to be interested.
“For me, he is a top player.”
