I don't think Madrid spending 80m on Bale has made any difference at least atm . Bale hasn't made Real Madrid any stronger than they were . It just demonstrated their punching power in the transfer market .
Anything in this life is a learning process . Wenger , despite his stubbornness , is not stupid . He learnt from his mistakes . Back in the day , he used to get rid of players reaching their thirties and it was working fine . But when his youth policy failed , he realised he was depriving his team of the experience of old players that they needed . Now he rarely let them go unless they are not good enough or want out themselves . His philosophy of not spending is nearly come to and end . Who would imagine one day Arsenal would spend on one player ( Ozil) more than what United and City have done ?
Wenger is still the right for the job for me , despite some frustrations .
