Barcelona star Lionel Messi has urged the club to sign Liverpool playmaker Philippe Coutinho over Mesut Ozil. The Argentine has reportedly told manager Ernesto Valverde and club president Josep Bartomeu to prioritise the Brazilian over concerns about Ozil's frequent dips in form. The Arsenal wantaway will be out of contract in the summer and could leave Arsenal for free, four years after signing for £42 million. According to the report from Diario Gol, Messi is keen for the club to sign a young midfielder and believes Ozil, 29, is too old. He would prefer to wait until June to sign Coutinho, 25, rather than settle for Ozil in January.
