The loan was actually £25m - With numeracy skills like that I am beginning to think you could be Peter Storrie (or at least spend time with him socially). Let us not forget what the loan was for:
"Gaydamak took out a loan with Standard Bank before a signing spree that helped the club win the FA Cup and qualify for Europe for the first time, but they have hit trouble since and the owner wants out."

Looks like Standard Bank could see the writing on the wall very early.
