I wouldn't panic about us only signing 3 new players - particularly at this time. It would be worrying if we'd signed no new players, all the kids rejected their contract offers and if we still had most of last year's dead weight contracted to the club.
Instead we've got some very promising young players now contracted to the club, most of whom have all had some sort of league experience, even if only a few sub appearances. Also, we've got rid of much of the chaff from last season and we've picked up 3 pro's with at least some league 2 experience, which at this stage in the summer isn't bad.
The next few weeks are likely to be packed with 'a trialist' 's, even more speculation and a number of signings*. Bring on Mansfield!
