Why does it matter who other teams have signed? I want to see an Everton team that plays the best possible football it can. That means having a starting line up that is strong in every position, with a proper tactical shape. Not one where we have to mix and match players to fit into a 4-5-1. It is a shame really that even now, after quite a few seasons of playing the same system, we do not have a first eleven that really looks complete. Hence we need to sign some players. Continuing to fill in the gaps with loans and small time players simply isn't the way to go about it. David Moyes should have a vision of how he wants Everton to play and summer transfer activity is the way that vision becomes a reality. Considering pre-season is usually when the shape of a team comes together, the fact that we have three integral players out with injury and are yet to sign a single player is worrying.
Incidentally, if you really want to compare us with other teams, I'll make the same point as in another thread; Manchester United, Liverpool, Chelsea, Arsenal, Manchester City, Aston Villa and Tottenham have all signed 10m+ players. In my book they count as 'big' signings that are acquired with the view to immediately improving the team. Everton, meanwhile, have signed no players at all.
