Arsenal need a family man to replace Wenger. Wenger has spent the ebst part of 20 years looking after all areas of his players, from youth players to seniors onwards. That is why they develop such good players, and have the right scouts to find them as well. It is not to do with 'do as i say' mentality it is one big family and the likes of Fabregas would never have left if it wasn't barcalona calling him. RVP left for money/ success considering his career to that point was injury plagued and needed the quick get out to win something on his own two feet. Otherwise he would still be there.
Any other arsenal player who has not been forcably sold so to speak has been happy to stay because of Wenger.
therefore It is not the style on the pitch Arsenal will look for, it will be the style off it. Martinez will end up at barcelona one day IF he takes us to the champions league and does quite well in it.
