The transfer market has gone absolutely bonkers, with mega-money moves being announced weekly.
However, some clubs have been rather savvy with their business this summer, bringing in some superbly talented footballers for nothing. Sure, their wages will no doubt be slightly higher to compensate for the lack of a transfer fee, but top teams are still saving themselves from having to fork out enormous sums to rivals.
There have been deals that have come out of the blue, as well as ones that were painfully obvious. Some are good, some are bad and some are just bizarre.
