Rangers legend Derek Johnstone has slammed winger David Templeton in an interview with the Glasgow Evening Times.
Things are finally starting to look up at Ibrox, with new manager Stuart McCall leading something of a revival in Glasgow after many dismal months.
After two draws in McCall's first two games, Rangers have now won three in a row, including the 2-1 win over champions Hearts on Sunday.
Goals from Kenny Miller and Haris Vuckic handed Rangers all three points at Ibrox, and now the club are in pole position to land second place in the Scottish Championship.
The squad appear to be much happier under McCall than they were under previous managerial staff Ally McCoist and Kenny McDowall - but one player has crossed the line somewhat.
Winger David Templeton, formerly of Hearts, lauded McCall and his training methods last week, as reported by the Daily Mail, but in doing so, launched a stinging attack on McCoist - which hasn't gone down quite as well as he'd imagined.
Now, former Rangers striker Derek Johnstone, who played almost 400 games for the club, has told the Glasgow Evening Times that McCall should be unhappy with Templeton - adding that the 26-year-old wide man hasn't been good enough this season.
"I thought his comments about the coaching at Rangers last week was the wrong thing to say and I don't think Stuart McCall would have been happy about it either," said Johnstone. "David is one of the 'stars' that was signed and was expected to do big things at Ibrox and he hasn't delivered."
"If anyone can have a go at the manager, it shouldn't be him. I don't think it can come from someone who hasn't done enough and has underachieved big time," he added.
