In June 2001, Plasmati left for Calcio Chieti of the Italian Serie C1, following several impressive displays in his early years for his prior clubs.

Plasmati obtained regular playing time for another season and went on to score a fairly impressive 12 goals in 31 league appearances.

Following two impressive seasons, back-to-back, the big striker was acquired by newly promoted Serie A side, Calcio Catania.

This proved to be his only appearance for the duration of the season, as he was behind Giuseppe Mascara, Gionatha Spinesi, Giorgio Corona, Takayuki Morimoto, and Fausto Rossini in the pecking order.

He was confirmed by Catania head coach Walter Zenga for the 2008–09 season, following the purchase of the remaining share of his contract from Foggia.

Atalanta had the option to buy half of his contract at the end of the season for a sum of €1.5 million,[citation needed] but opted not to, and hence he returned to Calcio Catania in June 2009.

[1] Following Atalanta's decision to not buy the player outright, Plasmati returned to Catania and was re-inserted into the first team by new coach Gianluca Atzori.

The player fell down the pecking order under his new coach behind Maxi Lopez, Giuseppe Mascara, Takayuki Morimoto, and Jorge Andres Martinez during the 2009–10 season, before being excluded from the first team at the start of the 2010–11 campaign due to financial and contractual problems.

The player was likely to be either sold or released anyway, due to the presences of several strikers above him in the first team pecking order, including Mascara, Lopez, and Morimoto, along with new arrival Mirco Antenucci, and later Gonzalo Bergessio.
