The 22-year-old’s agent, Fulvio Marrucco, claims the midfielder is back to his best form.
“Marek has returned to his excellent levels,” Marrucco said to Novantesimo.it.
“Marek wants to do really well with his national team, and especially Napoli.
“With the players applying themselves even more so this season, the team can compete for third place.”
