Fitness will be the theme in Austria this week but for a couple of Celtic players the next ten days will go along way towards deciding their future.
Two years into his reign Brendan Rodgers probably still has more players than he would like as he tries to shape up a lean squad of 20 players bolstered by young emerging talents waiting for their chance.
Ewan Henderson, Stephen Welsh, Regan Hendry and Kerr McInroy can supply the youthful element with upto half a dozen players needing to pull out the stops to be part of the season ahead.
Despite impressing out on loan at Hibs and Aberdeen it’s highly likely that Scott Allan and Ryan Christie will be following Liam Henderson out the door.
While Rodgers will analyse everything coming back from the training ground it’ll be in matches that players have to prove their worth.
Once Celtic return from Austria they will be straight into a routine of midweek European matches where no experiments can be taken.
Weekend matches will be for the fringe men, the A-Team will be involved midweek with no margin for error as Rodgers aims for a third successive season in the group phase of the Champions League- and a windfall of close to £40m.
