His manager says Rangers have "missed him sorely". Former Ibrox player Neil McCann says "he's got everything". He is the Scottish Premiership's top scorer and has now netted 27 times in all competitions this term.
On his return from suspension, Alfredo Morelos rattled four goals past Kilmarnock in Rangers' 5-0 Scottish Cup last-16 replay rout.
The Colombian has been red-carded four times this season - albeit one was rescinded after an appeal - with some pundits calling him a "liability" and "petulant".
But on Wednesday, Steven Gerrard's top marksman demonstrated how devastating he can be when his discipline holds and his quality shines.

'He showed we've missed him sorely' - reaction
The shellacking propelled Rangers into the cup quarter-finals, where they will travel to Aberdeen - a team against whom Morelos has been red-carded three times this term.
In the five domestic games Morelos has missed this season, Rangers have only scored two goals - and those came against struggling Dundee and Hamilton Academical.
"He was a constant threat. He deserved his four goals. He showed again we've missed him sorely in certain games this year," Gerrard told Rangers TV. "I'd also like to praise the support cast tonight, Candeias getting assists, Ryan Kent getting an assist."
'He's got everything' - analysis

When you're defending set-pieces, you're looking at the big men coming up, but you can't take your eyes off Morelos. Although he's not a big man he's got some leap, and with the leap comes the power. He's strong enough in the air but his all-round ground ability and strength is exceptional.
He's got everything - and that's why he needs to sort his temperament out. If he just channels it in the right way, without being disrespectful to Rangers, they'll cash in on this guy because a lot of teams will be looking at his goal-scoring exploits.

Morelos can score different types of goals. He scored a right-foot shot, a left-foot shot, a header getting in at the back post, showing great positional sense. Three of his goals were first-class.
The only incident he was involved in was at Daniel Bachmann's ordering-off. Alan Power was trying to lift Glen Kamara off the ground and Morelos got involved in that and had to get pulled away. He was getting involved there when there was no need - that is the big problem Rangers have with him, because other than that, he's got a lot to offer.
