In an age where money is quite literally everything in this sport, it’s easy to forget that some of the most effective players in Premier League history were free transfers. If you need proof, here are nine of the best.
When Sol Campbell made the move from Tottenham Hotspur to rivals Arsenal, it's pretty surprising that he wasn't immediately shot by Spurs fans.
It turns out, it was a phenomenal free transfer on the Gunners part as he went on to have five thoroughly successful years at the club.
Michael Ballack already carved a great legacy for himself at Bayern Munich and Bayer Leverkusen, but that grew even further at Chelsea through his continued solid performances week in and week out.
One of the best things to go from Germany to England ever, probably.
What can you say about the big American that hasn't already been said?
The bloke is an absolute tank and when Blackburn signed him on a free transfer following his stint at Liverpool, they couldn't have dreamed of the kind of consistency they'd be getting over the course of his eight years at the club.
Insert Steven Gerrard joke here.
Ba had an unreal tenure at Newcastle United following his brief spell at West Ham, and it's no wonder that Chelsea came calling as he went on a mad scoring run for the Magpies. Then again, that's more down to strawberry syrup than his actual abilities.
If this isn't the definition of an inspired signing, I don't know what is.
McAllister joined Liverpool at the age of 35 and whilst many thought the Scot was past his prime, he proved them all wrong in a big way by helping the Reds towards a famous treble.
Pretty self explanatory this one.
After a phenomenal first stay at White Hart Lane, Klinsmann returned years later on a free transfer, with the wonderful German's goals helping the club to avoid relegation.
I mean, just look at him, was he ever NOT going to drag them out of the shit?

Many people thought they were high on acid when they saw that Cambiasso had made the switch from Inter Milan to Leicester City, but alas it was true.
In his one and only season at the club he helped to guide them to safety which led to him being voted Player of the Year. Solid.
After spending 11 years becoming a Boro legend, some thought Schwarzer - and good god were they wrong, with Fulham reaping the rewards.
The things Jay-Jay Okocha couldn't do with a football at his feet weren't worth doing.
The man, who was so good that they named him twice, lit up the Reebok Stadium after moving on a free transfer from French giants PSG, and during his four years at the club he was pretty much the greatest man in the world.
