Famously, the January transfer window is the more difficult of the two to operate in. It's hard to persuade other clubs to give up assets mid-season, sometimes even harder to convince players that they're better off making a move immediately rather than waiting until the following summer. But that doesn't mean deals are impossible, or that you can't get good value for your buck.

January is a notoriously bad time for buyers because nobody ever wants to sell top talent midway through the season. There are, however, exceptions to the rule. Some clubs need to raise funds to balance the books, while others can be left with not option but to unload an unhappy player who has made it clear that he wants to join a stronger side.

Paris Saint-Germain have poached one of Barcelona’s brightest talents, with Dro Fernandez completing a controversial €8.2 million transfer to the French capital. The move has sparked fury in Catalonia, with club president Joan Laporta blasting the teenager's camp for breaking a verbal agreement regarding his future in what he described as an 'unpleasant' surprise for the Spanish giants.

Barcelona boss Hansi Flick has taken a thinly-veiled swipe at the people advising wantaway starlet Dro Fernandez after the midfielder edged closer to leaving Camp Nou, with Paris Saint-Germain his most likely destination. Fernandez has reportedly paid off his own release clause in a desperate bid to force through the move, which has incensed Flick.
