In the final days and hours of the January transfer window, Chelsea were heavily linked with Napoli striker Dries Mertens. 

Like Olivier Giroud, the man he was supposedly going to replace, Mertens’ contract was expiring and it didn’t sound like he was going to be able to work out a new extension with his employers. But unlike Giroud, Mertens wanted to stay with his team, hoping to become their all-time leading goalscorer. He was just a few behind Marek Hamšík, who had broken Diego Maradona’s record a couple years prior.

Mertens is still waiting to do so. He managed to draw level with Hamšík on 121, but then he got injured and then the season was suspended due to the coronavirus pandemic.
