Former Rangers player and manager Stuart McCall has told Sky Sports that he thinks Celtic boss Ronny Deila may need to win the treble this season.
McCall, who left his position as Rangers manager at the end of last season as the Gers went with Mark Warburton as his replacement, is currently working with the Scotland national team alongside Gordon Strachan.
In that role, McCall works with the likes of Scott Brown, James Forrest and Leigh Griffiths, all of whom are regulars in the Celtic side under Ronny Deila.
The Bhoys are expected to win the Scottish Premiership again this season, but manager Deila has come in for stern criticism this season over the club's performances in Europe.
A Champions League exit at the hands of Malmo infuriated Celtic fans, and then crashing out of the Europa League in a group containing Ajax, Fenerbahce and Molde only worsened matters.
Some fans have begun to turn against Deila and are looking for the club to replace him, prompting McCall to have his say on matters.
Speaking to Sky Sports, McCall was asked what is next for Deila amid questions over his future - and McCall believes that Deila may need to win a domestic treble to keep his job.
"I think Ronny has got to go and win the treble, I really do - or certainly a double." said McCall. "Although Aberdeen have picked back up a little bit and are pushing Celtic a bit more, I think Celtic's squad is too strong, and will go on and win the league. But I think for Ronny, at the end of the season, he needs to add another two cup competitions at the end of it," he added.
