Barcelona: Barcelona coach Xavi Hernandez called on Joao Felix to use criticism from his former Atletico Madrid team-mates to motivate him when the teams meet on Sunday in La Liga. The Portuguese forward, on loan at Barca from Atletico Madrid, failed to convince coach Diego Simeone during four years in the Spanish capital. Atletico playmaker Antoine Griezmann this week said Felix lacked “consistency” or “got tired” of finding it, while midfielder Saul Niguez also said Felix had plenty to improve on. Simeone said Saturday he did not want to speak about the forward because he was not at the club, despite still being an Atletico player. “(The criticism) should be extra motivation against Atletico,” Xavi told reporters Saturday. “I see he is motivated and happy, he is being consistent, I am happy with his performance and how he has adapted to the group.” Barcelona loaned Atletico’s record 126 million euro ($137 million) signing in the summer and after an impressive start, he began to struggle. Felix scored his first goal in 13 matches against Porto on Tuesday as Barcelona secured qualification to the Champions League last 16.
