Next season we are playing a new very progressive system. It's difficult to explain in regular terms, but it comes down to 3-7.
But's it's not really an overload, last season the problem was a lack of attacking players. With Maxi probably heading off, together with Bundi and hopefully Cole you aren't left with a huge amount of options. So it will probably be a AM set of 3 from Suarez / Kuyt / Gerrard / Diego? / Downing/Mata? with behind that a set from Lucas / Spearing / Aquilani / Adam? / Henderson.
Out of those you would have Lucas with either Aquilani or Adam as first choice with Henderson and Spearing as back-up. For the AM's you would have Suarez Gerrard and one from Kuyt and the possible signings. With Kuyt and Suarez mixing it up as a 2nd striker.
Looks a solid squad to me.
