Palma joined Celtic from Aris Salonika towards the end of the summer transfer window and has so far made six appearances for the club.
He is gradually getting into the groove of things and has had three goal contributions, including two goals, in his last three league appearances for the Scottish giants.
Liel Abada’s injury means Celtic are likely to depend on Palma in the coming months and Donnelly has been impressed with what he has seen from the player thus far.
The winger joined Celtic with a big reputation and the former Bhoy is pleased to see that he is not just relying on pace while playing in the wide areas.
He believes Palma’s willingness to play makes him a very different weapon in the Celtic armoury in terms of wing options.
Donnelly said on Clyde 1’s Superscoreboard: “I like the guy Palma. I think there is a lot more in there with him.
“He is beginning to contribute; the pass at the weekend was fantastic.
“Abada is out obviously.
“He has been brilliant for Celtic but he is out injured.
“This lad has come in; he has got a big reputation.
“He is different to what Celtic have in the wide areas.
“He looks to me as a footballer; he wants to come in and play rather than rely on pace on the outside.”
Palma will be hoping to start when Celtic host Atletico Madrid in the Champions League at Parkhead tonight.
