Barry Ferguson says he would've worked hard on the training pitch with his Rangers team instead of heading to Loch Lomond for a swim after their 2-0 defeat to Hearts on Saturday.
It comes after the players were pictured going up Conic Hill and taking a dip in the water on Monday afternoon as Russell Martin sought to build team spirit following the defeat.
Ferguson, who spent an interim spell in charge of Rangers at the end of last season, wasn't having it.
Speaking on Go Radio, he said: "Look, managers have all got different ways, maybe to take them out of the environment for the day.

"But for me, I would be on the training pitch and making sure I am getting a team ready to rock on the Saturday in the quarter-finals against Hibs."
Having amassed four points from their opening five league games, Rangers currently sit 10th in the Scottish Premiership.
They could drop to the bottom of the table by the time they next play in the league.
"We all know it [Ibrox] is a tough place to play but you need to be able to handle these situations," continued Ferguson.
"I have always said it, the Rangers fans are very demanding and that is the way it's been since I have been following the club and it will never change.
"You need to be able to handle those situations.
"When you are getting noise from the stands you need to be brave and want to take the ball.
"Overall, it has not been good enough. The performances and results have not been good enough and that just continues to pile the pressure on.
"First five games, four points. That is not good enough. there is no getting away from that and it needs to change quickly."
