March 4 (Reuters) - Barcelona midfielder Gavi is a doubt for Wednesday's Champions League clash at Portuguese side Benfica in the first leg of their last-16 tie, manager Hansi Flick said.

A clear example of this is Gavi, who approached Florentino Pérez to thank him for a kind gesture the Real Madrid president had with the Spanish player.

Barcelona fans online were unimpressed with La Masia graduate Gavi for his performance during the first leg of the Copa del Rey semifinal against Atletico Madrid on Tuesday (February 25).
