Los Che will face Atalanta in Italy on Wednesday night for the first-leg of their Champions League round of 16 tie.
"Many might've thought this was a good draw for us, but Atalanta are a quality team who find the net with many different players," Soler told Sky Sport Italia.
“Papu Gomez is their best player, those who only know him for his dance are really missing out."
He added: “I think the decisive leg will be at the Mestalla. Alessandro Florenzi spent many years at Roma, so he will be useful in giving us pointers on facing Atalanta, while I also spoke to Fabian Ruiz at Napoli. He said they are tough, but we have studied them carefully."
