Udinese sports chief Fabrizio Larini has announced the arrival of several new signings.
Udinese have reinforced their squad going into the Champions League preliminary round.
Larini revealed: "The objective is to maintain a competitive side, which is why we are also proceeding in new signings for the future. Along those lines, the Udinese jersey will be worn by Flamengo midfielder Willians, who is already mature, and Vasco da Gama's very promising youngster Allan.
"We'll also have Gabriel Silva, the former Palmeiras defender who spent last season on loan at Novara, Serbian goalkeeper Zeljko Brkic who was at Siena and naturally Luis Muriel, the very talented striker who played for Lecce. He has great quality and many big clubs have asked for him, but we'd like to see Muriel at the Friuli for a few years."
