The reputation of Tottenham midfielder Alli has exploded in Spain after his superb performances home and away against Real Madrid in the Champions League.
Messi believes Alli's games against Real only reinforced his belief that the midfielder could handle a move to Barca.
Diario Gol says Messi is pushing Alli's name forward to Barca as a potential successor for veteran captain Andres Iniesta.
Interestingly, as part of his new contract, Messi now has a formal say in transfer policy at Barca.
Alli, 21, is tied to Tottenham until 2022.
