As proven with recent results/performances, I believe the current squad is capable of finishing around the mid table position. The 'better' players out there won't join a club around the relegation zone come end of season, you say. If that is the case, why would they join us now?
But I do agree...
Singed?
Anyway, No, I don't think we need anyone else. We are not going for promotion, and the squad is good enough to avoid relegation.
Add on to that that Tony B doesn't like doing 'business' in January.
