I am preferring the signings of the unknown TBH. The good thing about that is that other teams have no idea how they play and so it could take time for them to be sussed out... by which time we can be well on our way points wise for the season.
Domestically, whoever we are looking at striker wise, so will Luton, Charlton and others. Hence it will go to a bidding war. An under the radar foreign signing seems more likely.
