The one-time Rangers midfielder was part of the discussion which followed Morelos' fifth red card of Steven Gerrard's Ibrox reign.
A quartet of BT Sport pundits, including the former Rangers midfielder, Alex Rae, and ex-Celtic strikers, Chris Sutton and Scott McDonald, have been debating what action the Gers should take with Alfredo Morelos.
Morelos was sent off for the fifth time this season as Rangers suffered a 2-1 defeat to their Old Firm rivals at Parkhead on Sunday.
The Colombian striker was subsequently fined by the Ibrox giants and suspended for four games.
He is, however, due to return for Rangers' final three Premiership fixtures, although McDonald doesn't believe he should play again this season.
"I didn't like what he said today (to a Colombian radio station)," said the Partick Thistle player on the network's St Mirren v Celtic preview earlier. "I didn't like him saying about Scott Brown doing this and doing that - just take responsibility for your own actions.
"I wouldn't play him again, not for the rest of the season. It could have been more (red cards). The only way to teach him is to scare him.
"If I was Steven Gerrard (the Rangers manager) now, in terms of position they are in the league, and he's going to be out for four games anyway, if they do do well in that period of time, and even if they don't, I still wouldn't play him until the end of the season. I'd leave him out.
"He has to learn.
But Stephen Craigan, a former teammate of McDonald at Motherwell, interjected, reasoning. "He's the only asset they have, that's worth £10-£12 million potentially. Then he's going to cost the club even more millions."
McDonald, however, replied: "But I think he's already cut his cost."
Asked by Sutton whether or not he would trust Morelos in a big game again if he were Gerrard, Rae answered: "Yes I would. Based on the goals he brings to the table. He's got 29 goals, more than any other player in Scotland. So that's the reason I'd go back to him. It's a no-brainer."
And on whether or not he thought Morelos was provoked, Rae responded with a dig at his former Old Firm rival.
"When, by Scott Brown? Not for me," he said. "But I've actually seen you get sent off in an Old Firm game and I'm not sure you were provoked too much that day."
Which (if any) of the BT Sport pundits do you side with over the Rangers striker?
