Rio Ferdinand has insisted Arsenal still need to buy a new centre-back despite their impressive defensive performance against Manchester City.
The Gunners sealed their place in the FA Cup final with a 2-0 win at Wembley on Saturday.
It was much-improved defensive showing from Arsenal, with David Luiz, in particular, standing out, whilst Pierre Emerick Aubameyang was clinical on the counter-attack as he netted a brace.
However, despite that improvement, Ferdinand believes that for Mikel Arteta to build towards an Arsenal team capable of winning the trophies, they need to buy a centre-back capable of forging a long-term partnership.
"No and he's (Arteta) not stupid enough to think it will (performance like today will win them the league)," Ferdinand told BT Sport.
"He seems very well educated football-wise. He knows exactly what he wants to achieve. I think as much as talent, it's about characters as well for this Arsenal squad going forward to keep improving on where they are.
"In their recruitment process, that's going to be key for them making strides in the right direction.
"I think they need to improve in most positions, apart from the front areas. I think Lacazette and Aubameyang are operating at the highest level.
"Pepe, still much improvement to see the player they spent huge amounts on that we saw at Lille but the potential is there.
"Defensively I still think, centre-back they need to buy, definitely. I don't think they have a partnership there. Any team that goes on to win things has a partnership there. It's the real foundation of any team."
