Chelsea have made more than a few transfer blunders over the years but most pale in comparison than that which sent Mohamed Salah to Roma. Initially a loan, the move included an option to buy the winger permanently, and the club eventually took the Blues up on that option.

He impressed over in Italy, and the rest is history. He is, of course, now at Liverpool - and he's playing a key role for the Reds who are in hot pursuit of the Premier League title ahead of Chelsea. Last season he enjoyed a remarkable run that transformed Liverpool's season, and he's continuing to impress this term.

It's clear now, then, that Salah is another name on a very long list of players that Chelsea gave up on too soon. He moved to the club from Basel, but after making a minimal impact during a minimal number of opportunities, he was quickly shipped out.

Significantly, former Chelsea manager - the boss at the time, when he was sold - Jose Mourinho has been discussing Salah's exit, and he's had something rather interesting to say on the matter. Speaking with beIN Sports, he's revealed that he didn't want Salah to leave, and that he wanted the player - that he had pushed to sign - to remain at the club.

The Blues, however, clearly went above his head, and the Portuguese is clearly unhappy about that to this day.

So, given Mourinho's apparent eagerness to hold onto him, it's worth looking at what Chelsea supporters thought at the time of his departure. Chelsea, as they always do, shared the news of the players' departure on Twitter, and though Salah wasn't the world-renowned star that he is today back then, the decision raised more than a few eyebrows. Indeed, it's fair to say that most Chelsea fans were furious - and you can see many of their responses below:

You'd expect that most Chelsea fans will be even more frustrated by the decision now, given how good Salah has been as of late. Losing Kevin De Bruyne and Romelu Lukaku for relatively small sums of money must hurt fans, but Salah? He's now perhaps the best winger in the Premier League - and Chelsea let him go.
