The Bulgarian hitman struck against his former club Bayer Leverkusen as we secured a place in the last 32 of the UEFA Cup with a 1-0 win in the BayArena on Thursday night.
That made it four goals in just three games in this season's European campaign having also scored against Besiktas and Club Brugge. He didn't feature in the first round legs against Slavia Prague
"Every time we play in Europe he is outstanding," said Martin at the BayArena. "In the league he's not there yet but he has all the talent - we are pretty confident he will be the same player he was in Germany for his last two or three seasons.
"He played for Leverkusen for five years and was a young guy when he came over, so he was a bit sensitive about this game.
"He said Juan knew him very well so I said maybe he could come up with some new tricks. The only thing was he could have scored a couple more - this was a night for four or five goals."
Indeed, Martin's only criticism was our failure to kill the game off as we broke away on numerous occasions, especially in the second half.
Dimitar missed from close range while home keeper Jorg Butt saved well from Robbie Keane, Mido and Pascal Chimbonda in the latter stages.
Bayer Leverkusen enjoyed their best spell at the start of the second half, Paul Robinson was forced into notable action on two occasions and Bernd Schneider cracked a 30-yarder against the post.
"We should have scored at least two or three more goals and in that situation you make it difficult for yourselves because it's still only 1-0," reflected Martin.
"If they would have scored it would have been one of the worst draws ever!
"We dominated them apart from one spell but you never know, in the second half we almost punished ourselves for not scoring.
"But I can't complain after a win like that. To be sitting on nine points after three games when two of those games were away to Besiktas and Bayer Leverkusen is a great feeling."
Martin Jol insists it's a matter of time before Dimitar Berbatov replicates his European form in the Barclays Premiership.
