When Chelsea sold fan favourite Juan Mata to rivals Manchester United last week, fans and players around the football world were quite shocked.
After earning the club's Player of the Year award in each of his first two seasons at Stamford Bridge, the Spanish international found himself on the bench for the majority of the first half of this season under new blues manager Jose Mourinho due to his low defensive work rate.
Many Chelsea fans were so devastated at the news of the Spaniard's departure to Manchester United that they barely realised the club had already found a replacement for him in the form of Mohamed Salah.
The Egyptian winger completed his £11million move from Swiss club Basel to Chelsea on Sunday and is now seen as cover for the likes of Eden Hazard, Oscar and Willian.
However, the 21 year-old has the potential to become something special at the Bridge and will maybe even make the fans forget the name Juan Mata.
He is an attacking midfielder capable of playing on the wing or in the so called 'number ten' role that Mata was so brilliant in in his time at the Bridge.
He has netted a brilliant tally of 17 goals in 27 appearances for his country Egypt. To give you an idea of how good that really is, England legend Steven Gerrard has scored 21 goals in 108 England caps.
Salah's goals and assists ratio is far better than what Mata's was at the age of 21 and Mata is now particularly famous for his goals and assists.
When Chelsea signed Mata at the age of 23 from Valencia in 2011, he was no where near the level he is today so the situation is similar to Salah, who has joined at the age of 21.
After netting against the blues in last seasons Europa league semi final, Chelsea's new number 15 scored home and away against them in 1-0 and 2-1 victories respectively.
Fellow Premier league club Liverpool were the favourites to sign Salah but Chelsea pounced as they immediately searched for an alternative for former hero, Juan Mata.
With the current strikers at the club not scoring as many goals as they would have hoped to this campaign, Chelsea have looked to their midfielders to score their goals.
Mata's tally of 33 goals in two and a half years at the club will be sorely missed especially with legendary goalscoring midfielder Frank Lampard out of contract at the end of the season.
Eden Hazard has not done badly this term with over ten goals in all competitions but the blues could look towards Salah for goals in the future if Hazard ever loses form.
Mata will always be loved and respected from his years at Stamford Bridge but this deal could end up being one of the greatest pieces of business in English football history if Salah can bring his eye for goal to the Premier league and show why Chelsea were right in letting a great player like Mata go and relying on the so called, "Egyptian Messi" to replace him.
