Transfer deadline day is a stressful day for just about everyone.
Players can often be left in limbo and be told they're on the move at the eleventh hour, forced to rush to training grounds all over the country for late-night medicals without any consideration for the families that may also be forced to move with them.
But few could claim to have it tougher than the agents themselves when it comes to stress levels. One man who knows all about how difficult deadline day can be is Dr. Erkut Sogut, who boasts the likes of ex-Arsenal duo Mesut Ozil and Kieran Gibbs as just two of his clients.
