Villa signed the France international from Wigan in a £9.5 million deal over the summer, but the winger has not shown the performances that made him such a hit at the Latics, and was substituted after an hour of the side’s 2-1 defeat to West Brom on Saturday.
Despite this, the Bulgarian midfielder has confidence in his team-mate’s abilities.
“A lot of people are on his back but we believe in him. We have seen it in training. Sometimes people need a longer time to settle in,” he told Mirror Football.
“We won’t give up on this boy because he is an important player for us. He will become good. He has been working hard and is looking sharper.
“It didn’t go well for him against West Brom but he will get back. We have a talent here and it will come a point where he starts playing well and scoring goals.
“We are patient with him and convinced he will come good,” the skipper concluded.
Alex McLeish’s men will look to bounce back from the defeat next weekend, as they travel to Wearside to take on Sunderland at the Stadium of Light.
