£9m is good business for Dawson, no question. But personally I'd rather hold onto him if he'd be happy to compete for his place. Losing Dawson, now that Bassong is gone, leaves us with Kaboul, Gallas, Vertonghen and Caulker as recognised centre-backs. Caulker may have a great future ahead of him (and I really hope he does) but fact is; none of us know for certain that he's ready to step up to premiership level this season. On top of that, Gallas is now 35 years old. Again, I hope he has a great season for us, but he's just one serious knock away from retirement. Let's hope Vertonghen is the Next Big Thing for Spurs, but he's unproven in the premiership and might take a while to settle in.
So what happens if 15 minutes into our match against Norwich, the day after the transfer window shuts, Kaboul gets injured and is out for a few months? Do we really want a 35-year old, an unproven youngster and a premiership newbie to be our defensive unit for the first half of the season? Because that has the potential to go very wrong indeed. I just don't think 4 CBs is enough for a team challenging at the top of the premiership. Not if one of the four is a kid and another is 35 with a history of injuries.
