James McFadden has claimed that Celtic would have to consider an offer from Southampton if they looked to sign Daizen Maeda.

The winger is reportedly attracting interest from the Premier League side after an impressive showing for Japan at the World Cup.

After Saturday's FA Cup victory over Crystal Palace, Saints manager Nathan Jones explained how he is in the market for "three or four" new players, and since then Maeda has been linked.

Asked about the transfer interest, James McFadden told Sky Sports News: "It depends what the offer is. I would never be surprised about any player leaving a club when there are millions involved.

"Maeda's World Cup was really good and his form has been excellent since he's come back.

"But Celtic are more than covered in every position on the park. I think he's shown an unbelievable attitude but I would not be surprised if any player left any club."

Meanwhile, Celtic manager Ange Postecoglou praised his new-look full-back pairing after they played their part in an ultimately comfortable victory over Kilmarnock.

Canada right-back Alistair Johnston made his home debut and Alexandro Bernabei made his fifth cinch Premiership start in place of the injured Greg Taylor.

With Anthony Ralston still out and Josip Juranovic on the bench, Postecoglou was happy with the way the selected pair adapted to the inverted full-back role during the 2-0 cinch Premiership win.

“It is a challenging position, it is fair to say that, because we are so different in the way we play from the way everyone else plays,” said Postecoglou, whose side created a series of chances after Jota broke the deadlock in the 45th minute.

“The likes of Ali and Berna are still getting their head around it. It probably took Greg and even Jura 12 months to get their head around it. All the guys have tackled it the right way, Tony Ralston is another one.

“The good thing about all those guys is they accepted the challenge. There was no saying ‘I can’t play that way’ or ‘I don’t like it that way’. They embrace it.

“With Ali and Berna, you will see the best of them as they get to grips with the role.”
