Alex McLeish reckons Giorgios Giakoumakis has made an "instant impact" at Celtic.
And he thinks Rangers have something to worry about if the new Greek hitman can keep the heat off Jota and Kyogo Furuhashi.
Giakoumakis was the Eredivisie's top scorer last season but injuries and an adjustment period meant he had a slow-burning start to his Parkhead career.
But he scored against St Johnstone in what is his only start for Celtic so far.
And he impressed again when brought off the bench against Hibs as Ange Postecoglou's team cruised to a victory.
Kyogo had earlier netted in that one and Postecoglou now has two very different centre-forwards to choose from in the Japan international and Giakoumakis.
But it's the latter who has caught McLeish 's eye as he told Football Insider: "Over the past few weeks and months, everybody’s been questioning if Celtic are going to have the power or the ammunition to stop Rangers from winning the title again.
“Some people were saying that they should win it easy. Now that Celtic are on a pretty good run, they’re on a good run of confidence.
“Giakoumakis, he looks a very lively centre-forward. A little bit of acrobatics in front of goal which he narrowly missed against Motherwell.
“He definitely looks the part. Taking the pressure off Kyogo with Jota, he looks terrific too. Giakoumakis, for all intents and purposes, looks a real centre-forward.
“When you see a player in his first game for his club and you see some things, you think he’s made an instant impact. I felt that with him.”
