Ralston has established himself as the first choice right-back for Celtic this season, but was the subject of a lot of criticism at the start of the campaign.
However, the 22-year-old has bounced back from the early setback and become a key player for the Hoops, scoring four goals from 20 appearances across all competitions.
Former Celtic star Wilson has been impressed with how Ralston has bounced back this season and hailed his contributions to Postecoglou’s side as outstanding.
Wilson pointed out how Ralston has also added goals to his game and went on to explain that Postecoglou is starting to rely on the Scotland Under-21 international.
Asked to prove his thoughts on Ralston’s contributions for Celtic this season, Wilson said on Clyde 1’s Superscoreboard: “Amazing, especially where he has come from.
“Started the season, not his fault that he was the number one right-back and took plenty of criticism for it, but he showed what a good player he is.
“And, to add goals to your game as a full-back just elevates you to a different level.
“I think he has been outstanding this season.
“I know he went through a wee tricky period where people were saying ‘He is back to the Tony Ralston of a few years ago’, but he has come through it.
“He plays every week and Ange Postecoglou is quietly starting to rely on him every week.“
Having scored four goals and provided two assists from 20 appearances this season, Ralston will be looking to continue his fine form for Postecoglou’s side.
