Atletico Madrid coach Diego Simeone is eager to see a deal completed for Sporting CP midfielder Gelson Martins.

Atletico's move for Gelson is heading for FIFA over confusion regarding the player's registration.

"I feel the club is constantly growing in a strong manner and that is necessary for the development of the team," Simeone told reporters in Singapore.

"Gelson is a player who is constantly improving. We saw it last year and his characteristics can help us.

"He will provide greater competitiveness on the right wing and offensively, if we play with three up front."
