Celtic youngster could start v St Johnstone after Welsh injury scare - pundit

Alex McLeish has suggested Ange Postecoglou could start a Celtic youngster against St Johnstone after Stephen Welsh’s injury scare.

The former Scotland manager, speaking exclusively to Football Insider, admitted losing the 21-year-old would be a big blow for the Bhoys ahead of Saturday’s League Cup semi-final.

Welsh, who was captaining Scotland under-21s, limped off with five minutes left to play in Tuesday’s 2-0 defeat to Belgium.

The academy product’s potential absence further limits Postecoglou’s options at centre-back.

Carl Starfelt may be a doubt for this weekend after suffering an injury before the international break.

Meanwhile, Christopher Jullien is still working his way back from a long-term layoff.

As such, McLeish suggested Postecoglou may have to resort to playing a youngster or a makeshift option at the heart of the defence.

McLeish told Football Insider’s Russell Edge: “You don’t want your momentum disrupted by injuries, especially the defenders.

“Normally they’re the nucleus of the team and they get a good rhythm playing together. Then all of a sudden you’re having to make changes.

“You’re possibly bringing in someone who’s not got much experience. That, or you’re playing another player from another position to try and cover that.

“That really can disrupt the momentum. That is definitely a problem for the coach.”

Welsh started Celtic’s last game, a 4-2 win over Dundee, alongside Cameron Carter-Vickers.

Summer signing Liam Scales, 23, could be an option for Postecoglou, having been on the bench against Dundee.

Midfielder Nir Bitton has also featured as a centre-back for Celtic already this season.
