The Old Lady are looking to strengthen their midfield in the summer and it is believed that they have identified the Portugal international as one of their transfer targets.Juventus are weighing up a summer bid for Chelsea midfielder Raul Meireles, Tuttosport reports.Fabio Paratici, sporting director of the Bianconeri, was spotted at Stamford Bridge on Wednesday to watch Chelsea\'s 2-1 Champions League quarter-final victory against Benfica.It is believed that Paratici\'s main task was to observe Meireles, who came on as a late substitute and scored the winning goal which confirmed the Blues\' progression to the semi-finals of the competition.Juventus are keen to add to their midfield options in the summer transfer window, with Lazio\'s Hernanes understood to be their top transfer target.However, the Stadio Olimpico outfit are holding out on their asking price of €30 million, which has forced the Old Lady to look for alternatives.Meireles signed for Chelsea last summer for an undisclosed fee at the request of Andre Villas-Boas, but with the Portuguese coach having been sacked last month, the Blues may be open to the idea of parting company with the 29-year-old midfielder, who has a contract until 2015.
