The 23-year-old midfielder has long been linked with a switch from the Emirates to the Nou Camp, to rejoin his boyhood club.
Former Valencia forward Villa hopes his Spain team-mate will join the Primera Division champions, and is determined to assist the move.
"I am not the Barcelona coach, nor the person responsible for reinforcements, but personally I will do the maximum to get Cesc here," he said in The Sun. "He wants to play here and it will be quite normal if Arsenal finally do a deal.
"That would be great. A player of his ability will only increase our power and his presence will be great for all the forwards.
"He'll help Xavi and (Andres) Iniesta, and I'll score more goals with him in the side."
