Erm, I think you'll find that Wenger did sign Overmars, Wenger joined Arsenal in 1996 and Overmars signed in 1997.
Are you trying to say that Wenger didn't spend big?
If you are you are talking through your backside, he had more to spend than the majority of clubs at the time on transfer fees and wages.
Paying a player £100k per week back in 2001 was unprecedented back then in this country as was the case with Sol Campbell.
I suppose you think that all of those expensive imports he signed such as Overmars, Petit, Grimandi, Kanu etc. or the expensive signings he inherited such as Bergkamp and Platt who became integral parts of his team were really born in Islington and played for free?
The fee for Vieira was 3.5m by the way not 3m -

This was still a big fee back in 1996 and certainly bigger than the majority of clubs he was competing against could afford at the time, especially for what you would class as a "reserve" at another club.
Wenger is a hypocrite, constantly bitching and moaning about City with his snide digs about "financial doping" yet conveniently forgets that Danny Fiszman bankrolled Arsenal in what would be the equivalent of £1.5 billion in today's money on transfer fees and wages.
Arsenal not for the first time in their history had someone come in and back them financially which is fine, but when the likes of Wenger and your entitled fanbase whine about others spending and try to imply that everything Wenger did was on a shoestring then it comes across as a tad hypocritical.
I love the way you cling on to this unbeaten in the league mantra, that 90 point season wouldn't have won the league in 5 of the 6 full seasons that Pep has been managing in the Premier League, but if it makes you feel good then fill your boots.
Pep has won as many league titles in 6 full seasons in England as Wenger managed in 22 full seasons and despite all the bollocks spouted about spending by the likes of Wenger, he hasn't got "unlimited funds" to spend.
Wenger also didn't have FFP regulations to worry about when he was spending Fiszmans' cash.
Wenger was happy enough to spend Fiszmans' money but threw his toys out of the pram when bigger fish with deeper pockets such as Abramovich and Mansour came along and upset the cosy little cartel set up by yourselves and the other entitled red shirts.
