Pat Bonner has suggested to BBC Radio Scotland that Alfredo Morelos's profligacy means that he cannot consider himself a top player for Rangers.
The Rangers marksman has courted criticism after missing a last-minute open goal in the Gers' 3-2 defeat by Old Firm rivals Celtic at Ibrox this afternoon.
Morelos, a £1 million signing last summer, hit the post from point-blank range after Scott Bain saved well from Josh Windass in the closing stages of a thrilling derby.
The 21-year-old South American has netted 17 goals in all competitions this season, but Bonner believes that Morelos, who also missed a great opportunity earlier in the second half, is being held back by his inability to come up with big goals on the biggest of stages.
He told BBC Radio Scotland: "Morelos has done OK, but he misses so many opportunities too.
"Top strikers, they put those away don't they? It came quickly, but he had enough time to adjust his feet to see it hit the back of the net."
Bonner might well be right. After all, Rangers could and probably should have beaten Brendan Rodgers's side at Parkhead in December, though another wasteful display from Morelos cost his side two points that day.
That being said, he is only 21 and it's his first season in Scotland. There is every chance that Morelos, in time, will develop into precisely the type of key player that the Hoops legend is suggesting that he inherently isn't.
