Former Arsenal defender Martin Keown has backed the north London side's pursuit of Liverpool forward Luis Suarez.
The Gunners have so far had two bids rebuffed for the striker but Keown believes manager Arsene Wenger is right to be chasing the Uruguayan international.
Keown also insists that Arsenal's two bids show that the club are changing their approach in the transfer market.
"It was a demonstration to Arsenal fans," said Keown.
"The club were saying 'We have £40m there. We have tried to buy someone else's best player for a change'. It has shown how serious Arsenal are about spending money.
"In the past, Arsene has nurtured them, then lost them just when they are at their best, as was the case with Samir Nasri, Cesc Fabregas and Robin van Persie.
"Now he needs to go out and buy an obvious talent, someone who is going to hit the ground running, and they don't come cheap.
"Fair play to Liverpool for hanging on to Suarez but Arsenal still need to buy two or three players. If they do, I think there is a real chance."
Arsenal have so far only managed to bring in France starlet Yaya Sanogo to the club but Wenger is hopeful he can add to his squad before the end of the transfer window.
Keown believes a player of Suarez's calibre would have a similar impact on the team as to what Dennis Bergkamp had when he joined Arsenal in the 1990s.
"Arsenal won 10 and drew two of their final 12 games last season. That was championship form," added Keown.
"I just feel if you are in the camp, you need a new signing, someone who makes you believe you are going in the right direction.
"It happened for us with Dennis Bergkamp. People asked why we were signing him.
"They didn't think he was going to be there for long but he ended up being one of the most successful overseas players ever to play in the Premier League.
"Maybe someone else can come in and do the same thing."
