I was firmly in the "give Moyes more time camp", but since he's gone, signings aside, the whole club seems to have taken on a new lease of life. van Gaal being appointed, the general mood coming out of the club all seems better. Add that to us getting some good transfer business done early giving those lads a chance to settle in and get a good pre-season with the team and it's easy to see why we'd be optimistic going into next season. Herrera alone is such a great signing, simply because he is a quality player in an area where we were really struggling. While I want, and expect another signing or two, I reckon with the new manager and the two new additions we'd be back battling for the top four if we went into the new season as we are now.
Obviously we want more than that, but that's how much I think we've improved already this summer, and the transfer window isn't even open yet.
