Yeah, well it depends on the tactics you're gonna go for I suppose. If your'e going to be a counter-attacking side like the current United one or the Chelsea 04/05 one then you absolutely have to have fast wingers.
By contrast, the current Man City side prefers to attack through continuous ball retention, looking to get players into holes, and neat short passes. Typically Italian through Mancini I suppose. There's no amazing pace in their side, but with Tevez, Aguero, Nasri, and Silva they've got players who can find space and open up a defence.
Spurs and Arsenal have gone for a bit of both worlds; through Walcott they can attack quickly, then they've got the Rosicky's, RVP's, Benayoun's - who want to get in between the defence and the midfield. Spurs are the same - attack at pace through Bale and Lennon, if that doesn't work then you've got Modric, Kranjcar and VDV who can go the other way. Their issue is that their squad just isn't big enough.
I like the idea of having both options. Away from home you absolutely 100% have to be able to counter at pace. Teams will come at you more and there'll be more open space. Being a counter-attacking side at home is pointless, cos teams come to Anfield and park the fucking bus. Which is why the City approach of having quality players who can find space in tight situations is imperative. Look at City's home record - amazing.
Just to add to this point above. It kinda highlights to me - again - how utterly fucking ridiculous the signing of Carroll was. He doesn't fit into either of those styles of play. Or any real style of play that a top side should be aspiring to be playing.
It was a monumentally bad bit of business. But anyway, Maxi.
