From the new article on the O/S, it looks as though someone at the club has taken note of these comments!
It makes sense for the club to have a look at players in training and maybe a pre-season game before signing them, so I've got no problem with this - much better than signing them without seeing them in action.
The only thing to be wary of is other clubs stealing players from under our nose before we've signed them, but this can work both ways (sounds as if Corby expected to retain Jordan Fairclough).
There are so many players looking for new clubs every summer that we should be able to get a decent selection of trialists and hopefully fill the gaps that we have in our squad.
Personally I hope SWD does sign for another year - all our strikers were troubled by injuries last season, and until he picked up an injury SWD was scoring plenty of goals. If they all have a good pre-season and stay fit, we should be looking for 40 goals in total from Newsh, SWD + a target man (Mikel or AN Other). If, like last season, two of them get long term injuries in pre-season, we could struggle for goals again.
