Lazio president Claudio Lotito is frustrated over the hold up for Santos midfielder Felipe Anderson's move.

Anderson's deal is stalling over third party interest.

"Anderson is a good player and should we be able to sign him, we will see him soon," Lotito told Radio Radio. "But we won't be conditioned by an attitude of extortion.

"The guy wants to come to Lazio, the clubs agree, but whoever has a percentage of his ownership is using it as a blackmail and I don't agree."
