Celtic boss Ange Postecoglou has claimed he knew defender Alistair Johnston was going to be a success at Celtic after speaking to the player for the first time.

The 23-year-old joined the Hoops in January from MLS side CF Montreal after a strong showing at the World Cup in Qatar.

Johnston has played 15 times for the Scottish champions so far this season, three of those matches being against rivals Rangers, and Postecoglou feels he has adapted well to life in Glasgow.

He said: "He loves a battle. I guess he loves these kind of games. When you try and bring in players, particularly to this football club, what I have found is that aside from their abilities as a footballer it takes certain types of characters.

"From the moment I spoke to him I knew he’d do for me. I finished off the Zoom call and said to somebody ‘he’s going to do well here.’

"He’s just a winner, he’s very determined to get the best out of his football ability. He’s embraced the culture here and embraced the responsibility he has.

"You know, in four months he’s had three of these games, three derbies, and I think he’s excelled in all of them."

Meanwhile, Fabrizio Romano has provided a transfer update on former Celtic defender Jeremie Frimpong.

Since joining Bayer Leverkusen in January 2021, the Dutchman has been linked away from the Bundesliga club several times.

And now transfer guru Romano has attempted shed more light on the situation.

He said: "Jeremie Frimpong, keen on Manchester United possible move. Not advanced yet as his agent has met with United, Bayern Munich and Barcelona.

"Interest in Frimpong does not change the situation of Diogo Dalot at this stage as the new long-term contract talks are still ongoing."

Celtic reportedly have a sell-on fee believed to be worth 30 per cent of the profit on his next sale.
