Dubai United Arab Emirates — Diego Maradona has taken another swipe at Pele, saying the retired Brazilian star must have taken the "wrong medication" when he suggested Neymar was better than Lionel Messi.

Speaking in Dubai on Thursday, Maradona acknowledged that the young Brazilian forward was good but insisted he never will be able to match Messi, the Argentine who is a favorite to win his third straight FIFA Player of the Year award.

Maradona, who coaches Al Wasl, has been at conflict with Pele for years. The two sparred last year when Pele criticized Maradona's coaching of Argentina during the 2010 World Cup.

Pele has said that Neymar was "technically" better than Messi, but that the Brazilian has a lot to prove if he wants to be considered the best player in the world one day. That didn't sit well with Maradona, who is currently the coach of the United Arab Emirates club Al Wasl.
