Frank Arnesen warns of a 'dangerous weapon' when Charlton arrive at the Lane on Saturday - the pace of winger Dennis Rommedahl.
The speedy Dane joined Charlton during the close season from Frank's old club PSV Eindhoven, the sporting director having seen at close quarters the qualities possessed by the 26-year-old.
While Frank knows what else the 44-times capped player brings to the table, he agrees the most striking factor is his searing pace.
"That is correct because it is his most dangerous weapon," stated Frank, who adds that it might take a little time before the Premiership sees the best of his countryman. "It is unusual to find a player with that sort of speed and he has done very well.
"When he was 18 and came to PSV it took him one or two years to settle in. He had a loan spell for a year, came back and progressed to being an international. Even though he is 26 he has got a lot of experience behind him.
"He is in a new environment, playing in a new competition and he needs a little bit of time.
"He is a very dangerous player, a player who managers will wonder how to stop him because of his pace. He has a good cross and can make goals, it is not for nothing that three years in a row he produced the most assists in Holland - many of the goals he gave to Kezman.
"It is always a danger when you are up against such speed and a good cross. I hope he will not be able to do it on Saturday."
Denmark appear to specialise in producing speedy wingers, what with Rommedahl, Jesper Gronkjaer and Martin Jorgensen featuring in the national team. Frank regrets to report that the production line in his homeland is stalling.
"Unfortunately, if you go to Denmark now, more teams are playing with midfield players on the side. I have always favoured wingers - one or two - and it is about having the quality to dribble and take a man inside and outside.
"These are the sort of players Denmark have in the national team, but I can't see many more coming through. It is a shame because I think everybody likes to see wingers playing in the old fashioned way."
