This article forms part of our Total Duds feature series, which is where Football Transfer Tavern takes a look at how a player has fared since being signed or sold, using statistical figures and statements from pundits to prove how bad a deal the club got.

Chelsea have signed some of the best talents over the years. The likes of Eden Hazard, Didier Drogba and N'Golo Kante all proved to be very impressive coups from the club. Each player has helped drive the Blues towards silverware during their time in London.

However, Chelsea don't always get their business right. One example of this is their decision to let Mohamed Salah leave for Roma a measly sum of £13.5m back in 2016. Jose Mourinho, Blues manager at the time of his initial loan move to the Serie A side, spoke out on this piece of business and admitted it wasn't his choice to let the Egyptian leave.

"First of all let’s start with Salah. Because lots of things have been told which are not true," he told beIN Sports (via Goal.com). "For a start people try to identify me as the coach that sold Salah. I am the coach that bought Salah. It’s completely the wrong idea."

Mourinho explained that the winger struggled during his time in west London, which played a part in his eventual departure. Salah joined Roma before being snapped up by Liverpool, with whom he has made himself one of the biggest stars on the planet.

The 28-year-old boasts 94 goals and 41 assists in 153 appearances for the Reds (via Transfermarkt). As well as his participation in their recent Champions League and Premier League titles, Salah has raked in personal accolades.

His first two seasons on Merseyside saw him win back-to-back Golden Boots. Additionally, the Egypt international broke Luis Suarez's record of most goals scored in a single Premier League season for Liverpool. Salah's 32 top-flight strikes in 2017/18 just snubbed the Uruguayan's 31 from four years previously.

After such huge achievements, Salah's Transfermarkt value has skyrocketed to a mammoth £108m. "When the club decided to sell him it was not me. I bought him, I did not sell him," Mourinho concluded.

Although it could be argued that Salah wouldn't have fit in at Chelsea, it still must be a sore subject knowing they could have retained him and unleashed his exceptional firepower.
