Absolutely. Traditional Roy Keane types are not as important.
Look at Barca in their prime....they used to press with high intensity with Busquets, Xavi and Iniesta in midfield. Busquets is never a hard tackling midfielder. But he was technically brilliant and part of a cohesive pressing system.
A- tika taka is dead. Even Marca admit that. The idea is great and all but you need a squad of players whose got superb passing skills and are in their prime to play such highly intense and passing obsessive football. No one can afford that.
B- Keane was never the oaf type of DM whose only good in defending and offered nothing going forward. He spent his early career as an AM (Forest and with us up until Scholes started playing in CM). In fact Sir Alex's spat with Incey was precisely on that matter. Ince wanted Keane to play DM instead of him and Sir Alex refused which lead to Ince ignoring Sir Alex tactical instructions during that infamous FA final against Everton which we lost. Once Scholes was introduced in CM, Keane spent did the lionshare in terms of defensive duties. However we needed that as he was the defensive focal point of a team who played 5 attacking minded players in it. Having said that Keane was still a great player going forward. He dominated Juventus in that famous semi final.
Defensive wise we're currently playing an older type of football then the one Keane played in. We've got a dedicated DM and two fullbacks who offers next to nothing going forward. That reminds me of the good old catenaccio system. Keane, Gaz and Irwin are far more modern style of players then AWB, Shaw and Matic.
My only concern with Keano is his attitude. He's got this old fashioned aggressive way of percieving football which was already a problem during Queroz time. Modern players have agents protecting them these days. They won't allow nutters who commit career threatening tackles on their clients during training just to point out whose the alpha male in that group
