Siena coach Alberto Malesani says Sampdoria are a better team without Antonio Cassano.
Since Samp coach Gigi del Neri axed the forward, the Blucerchiati have won three games on the bounce.
"With Cassano's exit they have strangely rediscovered their enthusiasm," explained Malesani.
"It's odd that the wind is back in their sails now. It's like they have been regenerated."
