Former Arsenal midfielder Freddie Ljungberg believes Chile's Arturo Vidal could help the Gunners challenge Chelsea for the Premier League title.
The Chilean endured a below-par campaign at Juventus last season but is a target for a number of top European clubs including Arsenal, according to reports.
The Daily Star reported on Sunday morning that a £21m agreement has been reached with Juventus and that Arsenal will announce the signing of the player at the end of next week.
"I think the players who are already there are great, but for me I want to see speed," Ljungberg told Sport360°.
"There were some rumours about [Arturo] Vidal, a great player, and he gets fuming if he loses the ball, so I like that. That kind of player would be great for the club.
"Look at Sanchez. After the World Cup in South Africa I said I wanted us to buy him, when he was at Udinese.
"He is quality but he also works hard as well. He has speed. When he loses the ball he still fights for it and that's what I like to see
"I hope they can challenge for the Premier League title.
"Now I feel like they started again. They bought Sanchez, who I think is an amazing player, they bought [Mesut] Ozil the year before that and splashed the cash a little bit.
"I think in one or two years we'll have a squad that's going to compete with anyone.
"With one or two signings here and there, we can get a stronger squad. We're getting there and I'm really looking forward to the next couple of years.
"If we go the way we've been going then we'll compete on the same level [with the likes of Chelsea and Manchester City]."
