Arsenal manager Mikel Arteta has assured supporters about the quality of new signing Fabio Vieira.

After an injury-hit preseason, the Portuguese midfielder made his debut in last weekend's loss to Manchester United.

Speaking in his pre-match press conference ahead of the game against FC Zurich on Thursday, Arteta said: "We were looking for players that could play in three positions in the frontline and in the attacking midfielder positions. We were looking for very specific qualities in the market and when I saw him, I really liked what I saw.

"Straight away, I was convinced that he was a player who can help us go to the next level and that he had the right personality and character to play for our club.

"It's a shame that we detected an injury when we were doing the medical. He had no pre-season and everything has been delayed, but hopefully you're going to see a lot more of him in the next few weeks, and I'm sure that you'll enjoy it."
