Basel's success this century coincided with them producing some fantastic players. These players went on to different clubs in other leagues and made their name.While we cannot discuss them all, we will be viewing five of the club's most expensive departures as listed by Transfermarkt:#5 Mohamed Elneny - €12.5 millionArsenal v Leeds United - Carabao Cup Round of 16Elneny is an Egyptian player who started his career at Al Mokawloon. Debuting at the age of 18, he earned his European call when FC Basel signed him on a six-month long loan in 2013. His move was made permanent before the new season began.The 29-year-old defensive midfielder earned a regular spot there and appeared 142 times in four years. He also managed to win the Swiss Super League every year and his performances there attracted the attention of Arsene Wenger.In the winter transfer window of the 2015-16 season, Arsenal signed Elneny for a fee of €12.50 million. He was their backup option, as a result of which he did not appear as frequently as he used to at Basel. Excluding a season-long spell at Besiktas, he is in his sixth season with the Gunners.#4 Mohamed Salah - €16.5 millionChelsea FC v Sporting Clube de Portugal - UEFA Champions LeagueMohamed Salah is another Egyptian player who had the same route map as that of Elneny. After a couple of seasons with Mokawloon, he moved to Switzerland where he joined Basel in 2012.Unlike his team-mate, he did not stick there long, as two years later, Chelsea signed him for a fee of €16.5 million. However, he failed to succeed at Stamford Bridge which resulted in him going out on loan spells. Roma finalized his permanent move in 2016 which saw a turnaround in his fortune.433@433😅 @didierdrogba on @MoSalah breaking his record to become the top African goalscorer in Premier League history 🌍1:43 AM · Nov 26, 202112265603😅 @didierdrogba on @MoSalah breaking his record to become the top African goalscorer in Premier League history 🌍 https://t.co/qIb32erzliA year later, Liverpool signed him and he delivered a record-breaking debut.
