@diarm if you see this as double teaming then apologies but I think you have been all over the map regards to midfield discussion so i will just clarify it once it for all.
Batty as per you is playing a role of pure DM, whose presence will a) stifle Bergkamp b) allow both full backs to push forward. At the same time you have also mentioned he will also be competing in proper central midfield area like Keane. Now there is a reason why dedicated DMs like Makelele mostly played in 433. Even someone like Matic does not play this kind of role of Chelsea even in 4231. He is more of a pure destroyer who will run about in midfield and break attacks rather than sit in front of the defense. If you do designate someone purely for that role, especially in a 2 man midfield you are leaving the other midfield a bit high and dry. Second, it is questionable itself if Batty will be able to prevail against likes of Bergkamp and Scholes.
To make it then sound like it is Keane and Scholes who have a bigger task in front of them is absurd. It is clearly Modric and Batty who will be stretched here. You seem to want to have your cake and eat it too where Batty will combat Bergkamp and equally be a participant in battle against Keane + Scholes
Keane is not playing as a pure DM here, neither does he needs to against someone like Tissier. Both him and Scholes are well rounded midfielders perfect for any 442. It is inherently an attacking midfield pairing. With Bergkamp in there it is clear as a day of straight up 3 vs 3 in the central area
- Keane + Scholes + Bergkamp vs Batty + Modric + Tissier
Regardless of wherever or whatever role you may want each of your 3 to play. The gulf in quality there is stark and will have an impact in any match.
