Walcott has two crucial assets at an exceptional level to ensure his success at AFC

So the day that London suddenly sees blue skies is the day that Theo Walcott becomes an Arsenal player!!

It's a good omen for a fantastic signing. This is a big day for AFC because Theo Walcott is an extraordinary talent. His signing also confirms the intent of the club to progress and meet the Chelsea challenge.

His distinct qualities are a perfect-fit for AFC: high technical quality, supreme speed combined with total balance, and a pure athlete/footballer. He compares to Michael Owen and Wayne Rooney as evidently magnificent young striking talents to be produced in England in the last ten years, and it is great for both him and AFC that his progression will be in an Arsenal shirt.

Walcott won't be able to find a better coach anywhere to maximise his talents than Arsene Wenger. The AFC manager is a master of developing gifted young players into fantastic footballers: Henry, Vieira, Cole to name just a few. Also, the ultra-quick and precise attacking gameplay of AFC is the best type of footballing system for a pure attacking footballer like Walcott.

Comparisons with a young Thierry Henry are spot-on. Arsene Wenger constantly refers to Henry as having 'unlimited potential' because of his amazing 'talent and motivation'. I agreed with Wenger when he first said this about Thierry- and TH is still living up to this statement.

I'm convinced we are going to hear the exact same phrase from Arsene Wenger when discussing the merits of Theo Walcott. For aside from his devastating talent, he also looks to have the other crucial asset necessary to take him right to the very top: a great mindset.

All the evidence I've seen indicates he has a fantastic temperament. This is a decisive quote from TW:

"Staying level-headed is the most important thing for me. I just want to play, improve as a player and play at the highest level."

I've heard him speak and he certainly comes across as level-headed. His demeanour on the pitch solidifies that impression. The Soton scout has talked about his great 'level-headedness'. And the former Soton player, Graeme Le Saux, has said he has 'all the mental qualities to go to the top'.

It's not enough to have great talent if you want to reach and stay at the very top over a long period of time. You need a world-class mindset too: just look at Henry, or Tiger Woods, or Roger Federer. It's great that Walcott has this vital asset and does - as the quote suggests - recognise the importance of it.

Walcott is only 16 years old. He is talented enough to make an instant impact for the team but his true worth lies in what he will bring to AFC over the next decade.

The addition of Walcott to a squad already comprising fantastic young talents like Senderos, Toure, Clichy, Fabregas, Reyes, Van Persie, Diaby, Eboue, Gilbert, Song, Hleb, Lupoli and Adebayor shows that Arsenal's future is looking very bright. Add a Captain Henry and a fantastic new 60,000 capacity stadium into the equation, and the potential definitely exists for Wenger's 'next-generation' AFC to emulate their predecessors.

P.S. Nice quote from Arsene on TW:

"His attitude is predominant. What happens until you are 16 is because you are a talented player. Between 16 and 18 your mental state takes shape and that shows how much you want to be a special guy, how much you want to be the best and that is the next step. I believe he has the ingredients in his personality to be steady, determined and motivated enough to achieve that.”
