Marek Hamsik's agent is unhappy with his treatment by Napoli coach Rafa Benitez.

Agent Juraj Venglos, interviewed by Radio Crc, has questioned why Hamsik struggles to see out games.

"I don't know why Hamsik is often subbed off," he said. "I must say that I saw him playing for the national team and I liked what he did.

"I'll say this again, I don't know why Benitez cuts his time short, but the important thing is that he plays.

"Though it must be said that you've got to be given playing time in order to develop the best physical condition and I can't figure out why he plays so little.

"I don't know what the player's mood is with regards to what's been happening over the last few weeks."
