Keown is a fan of Wenger's man-management
Arsene Wenger's decision to sign a new deal is great news with everyone associated with Arsenal.
I have to say there was some uncertainty over his future when vice-chairman David Dein left the club earlier this year.
Dein brought Wenger to north London and I'm sure the Frenchman would have questioned the club over the former vice-chairman's departure.
But now that he's committed he can continue to develop this young, capable team.
He was great to be around when I was a player - he's calm, considered and very intelligent.
Wenger treats all the players like adults, he always gets a good response from them and I don't think he actually fallen out with anybody who has been under his wings.
He has also been very shrewd with his signings during the 11 years he's been at Arsenal, having unearthed quite a few gems, without spending a lot of money.
This summer, he signed four players but maybe it would have been more had he agreed on a new deal earlier - but now he can go ahead with his plans.
The club has transformed into something completely different
I reckon it's going to be quite an exciting time at the Emirates Stadium.
Wenger has four more years and I think they will be his best years. He has more experience now, the team are playing at a new improved venue and there has been talk of new investment.
Arsenal is his baby. The club has transformed into something completely different to what it was before he came.
Wenger's challenge will now be to make the Gunners bigger than Real Madrid and Manchester United - and he has given himself every chance.
