The January transfer window is in full swing, with a number Premier League clubs desperately trying to strengthen their squad.
A good transfer window could be the difference between a club having a successful season or being left short and failing to fulfil their targets.
For sides down the bottom of the table, it’s arguably more important than for those at the top.
That’s because top-quality players are rarely available, while teams facing relegation will want a handful of fresh faces to try to turn things around and avoid the dreaded drop.
But that doesn’t mean there haven’t been big moves in January in the Premier League over the years – some have been good, some not so successful.
We’ve compiled the 15 biggest transfers in Premier League history in the winter transfer window, it’s up to you to try and work them out in our quiz below.
We’re only counting players who’ve arrived in England, rather than those who left in January, so Oscar’s move to Shanghai SIPG last year doesn't count. We're also counting the deals that have gone through so far this month.
Some transfer are memorable, while others were better off being forgotten.
You have eight minutes to get the 15 players, and make sure you turn off Ad Blocker so the quiz shows correctly.
