Foster was one of the players criticised by King following his takeover of Rangers, but he has suggested a worrying aspect of the playing squad following his departure from Ibrox in an interview with the Daily Mail.
The 29-year-old said: “Effectively, the 11 of us got blamed for the season last year but there were many different factors. If you look at the team from when Stuart McCall came in, the mainstays were the players who were going to be here this season.”
Foster has highlighted the fact that the first-team players who underperformed last term are set to be part of the team this coming season.
It was the likes of Foster, Lee McCulloch and Kris Boyd who were criticised, and then released at the end of their contracts, having only played bit-part roles during 2014/15.
Therefore, King criticised the players who had no chance to right the wrongs on the field of play, whilst overlooking the fact that Rangers will be starting next season with a squad comprised of players who struggled last term.
Players have already been brought to the club this summer, with Danny Wilson and Rob Kiernan two high profile names, but there is no denying the fact that the first-team squad will be largely comprised of players who failed to win promotion last season.
Hopes might be high at Ibrox right now, with a new manager and signings coming in, but Foster has highlighted the fact that Rangers will be very similar next season as they were during 2014/15.
