Unai Emery said, We are really excited and are really happy with him. For us, Moussa Diaby is one player we were following. I was very happy with the work we did last year, now this year we have to add some different players."
He added, “He’s helping us, trying to improve our level of play in the attacking third, sometimes playing on the right, sometimes he’s playing as a No.10 and sometimes he’s playing as a left winger. We have to build again our structure and Moussa is giving us another important step ahead.”
As per Aston Villa's website, the 24-year-old put pen to paper on his contract at the club’s Washington, DC hotel and met Emery before linking up with his new team-mates and the Villa boss spoke glowingly in his praise for the club’s latest summer signing, before revealing he is set to start training on Monday.
While concluding Unai Emery said, “He is a winger, a striker and his best part is his capacity to attack, dribbling, running behind,” added the Spaniard. He has experience in Europe, he’s young and I think the qualities he’s going to give us, playing in different positions as well, I think he’s going to give us more power. The idea is to start with us training on Monday, after the match tomorrow (against Newcastle).”
