You have a point there
Even if we spend all the £80 million its unlikely we can replace Ronaldo.
No but looking at todays squad, you could probably buy better Dm, CM, left and right wing, right back and be a far better team than todays was. You might not be able to get a single player whose better than Ronaldo, forget Ronaldo though, you can improve fairly easily on a good 6 positions in the squad.
Giggs, as he was last year but for the blind idiots, a fantastic player on his day, but with "his day" coming few and far between. Till Feb last year he was awful, had 2 great months and sporadically good till the end of the season. This year he's had 2-3 awesome performances, and some crap ones like today. Theres a heck of a lot of room for improvement in that squad.
But I'll again say it Berbatov is crying out for a Owen type to start regularly infront of him, why he's a big man up on his own I'll never know. LIkewise Rooney's single sustained unbeatable form long run of games, came at left wing. Frankly as today showed, his attempted throughballs in behind were poor as anything. His passings never been his strength, his best strenght is probably very powerful running, which from the wing he gets to do constantly, he's actually got a fantastic delivery from the wing, again something he doesn't use as a striker, and well, he's never been prolific, he played a LOT on the wing last year and still got the same kind of goals he usually got.
Considering he was so consistant there, and very inconsistant as a striker who doesn't work well as a front two with Berb's, its madness to play him there.
