Sampdoria general director Giuseppe Marotta insists Antonio Cassano's exclusion from the squad is simply a "technical choice".

Cassano has been left out of Samp's squad for the last three Serie A games, leading to speculation of a problem between Luigi Del Neri and the former Roma star.

"The relationship between Cassano and Del Neri is based on reciprocal respect and professionalism," said Marotta.

"His exclusion is a technical choice and there are no disciplinary reasons behind it."

Cassano's absence has not hindered Samp, who have won their last three league games, including last weekend's 2-1 win at Siena to climb to sixth in the standings.

The temperamental playmaker turned down a move to Fiorentina earlier this month and it remains to be seen when he will return to action.

"Cassano is a natural-born talent," said Marotta.

"Even if we have won our recent games without him, his presence and quality will help Sampdoria."

Samp host Fiorentina on Saturday before travelling to the San Siro to meet Inter Milan later this month.
