Doni: Alisson will show his signing was a bargain

Doni, who represented the Giallorossi between 2005 and 2011, played 10 times for Brazil - winning the Copa America in 2007 and going to the World Cup with the squad in 2010.

Now both Brazil and Roma's No. 1 shirts belong to Alisson, and their former holder believes the 24-year-old is ready to make a big name for himself.

Alisson grabbed headlines on Tuesday after a match-saving display against Atletico Madrid on his Champions League debut.

"I'm not surprised [by his performance]," Doni told Corriere dello Sport. "From the first day, I thought with regular playing time he would show his quality.

"Alisson is a great goalkeeper. You do not become No. 1 for the Brazilian national team through luck, things aren't how they used to be. After Taffarel we began to create an important school of goalkeepers: Dida, Julio Cesar, myself. Now it's his turn."

Doni believes Alisson's arrival in the Italian capital, and emergence as the starter after a debut campaign playing in the cup competitions, is a perfect arrangement for all involved.

"I am glad that Roma have got him," he added. "Indeed, I think it was a bargain. And for his part, he is in the right place to get better. Experience in Europe, and in European competition, is a huge thing for a South American goalkeeper - as long as they get regular opportunities to play."
