It would be a safe option to deploy Mikael Lustig at right-back against Rangers, but Celtic manager Brendan Rodgers should be brave and play Anthony Ralston instead.
Ralston is 18 years of age and has made only a handful of appearances for the Celtic first team so far in his career, but he already looks like a player with huge potential.
The Scotland Under-21 international right-back played against Paris Saint-Germain in the Champions League last week.
Although PSG hammered Celtic at Celtic Park, Ralston’s performance on the right-hand side was quite encouraging.
The way the teenage talent confronted Brazilian star Neymar and made him work hard underlined his ability to cope with big-name players in big matches.
The Old Firm derby is one of the biggest games in the world, and playing in front of a packed Ibrox against Rangers on Saturday afternoon is not going to be easy.
However, Celtic manager Rodgers should be brave and throw in Ralston against Pedro Caixinha’s side.
Ralston is the future of Celtic and become a superstar in the coming years, and the way he played against PSG and the temperament he showed suggest that he will be able to cope playing against Rangers.
