The 78-year-old Celtic legend, who played for the Hoops in the 1960s and 1970s, believes that he would beat the 25-year-old Australia international midfielder in a race.
Wallace told The Scottish Sun: “Tom Rogic? I have watched him a long time and I’d beat him in a race — even today!
“Rogic’s a good enough player, but put him out there when he has to look at the big picture? He’s not at the races.”
Rogic has not been in great form so far this season, although he has played in some games for Celtic.
The 25-year-old, though, is a very good and important player for the Hoops, who will need him to hit top form as the season progresses.
The Australia international has been on the books of Celtic since January 2013 when he joined from Central Coast Mariners for a transfer fee reported by The Telegraph to be worth £400,000.
The 25-year-old midfielder has scored 32 goals in 147 appearances in all competitions for Celtic so far in his career, as stated on the Glasgow giants’ official website.
Celtic are third in the Scottish Premiership table at the moment with 16 points from eight matches.
