Celtic legend David Provan has criticised Rangers in The Scottish Sun for selling Charlie Adam and Ross McCormack.
Midfielder Adam, now on the books of Premier League side Stoke City, joined Blackpool from Rangers in 2009.
Fulham’s McCormack, who can play as a striker or as a winger, left the Gers for Motherwell in 2006.
Provan, who played for Celtic in the 1970s and 1980s, has criticised Rangers for selling the two England-based players “for buttons”.
“Came across Charlie Adam at Stoke last weekend,” the former Scotland international winger wrote in The Scottish Sun. “He is struggling to get into Mark Hughes’ side right now, but Stoke’s £4million capture of the then Liverpool midfielder took Adam’s transfer fees north of £10m.
“Elsewhere Middlesbrough have had an £8m offer for Ross McCormack turned down but will up their bid. With 17 goals already this season McCormack’s £11m switch from Leeds has proved good business for Fulham. Makes you wonder why Rangers allowed both Murray Park graduates to leave for buttons.”
Rangers are playing in the Scottish Championship at the moment, but they are on course to gaining promotion to the Scottish Premiership at the end of the season.
The Gers are currently at the top of the league table with 50 points from 20 matches. Mark Warburton’s side are two points clear of second-placed Hibernian and have a game in hand.
Meanwhile, Celtic find themselves at the top of the Scottish Premiership table at the moment with 55 points from 23 matches, six points ahead of second-placed Aberdeen.
