Roma are said to be stepping up their interest in Argentine youngster Juan Manuel Iturbe, according to TuttoSport. A host of top clubs have been linked with the Porto attacker, currently on loan at Hellas Verona in Serie A, and Liverpool had believed to be leading the chase for his signature.googletag.cmd.push(function() { googletag.display(“div-gpt-ad-1389116196215-0”); });However, Roma have been watching his performances closely in recent times, and will hope to add him to their squad next season as they look to build on a strong campaign this year. The Italian giants lost some key attacking players last summer in Erik Lamela and Pablo Osvaldo, and the addition of a prospect like Iturbe could be a big boost for them. The 20-year-old has been compared to Barcelona star Lionel Messi in his style of play, and a bidding war for his signature looks likely in the next transfer window.
