Read the passage and answer the questions below.
His departure rescued Roma. His arrival revitalized Liverpool. When the two clubs meet over two legs in the Champions League semifinals, the matches will also serve as a celebration of Mohamed Salah, a player who means more to Roma and Liverpool than they could ever have imagined. The Egypt winger left Roma for Liverpool in June last year for 42 million euros ($50 million). In an off- season when the Premier League spent record sums and Neymar would soon go on to change the sport’s financial landscape by joining Paris Saint-Germain for 222 million euros, Salah’s transfer wasn’t unnoticed but was hardly agenda-setting. It has proved a significant piece of business. For Roma, it helped balance the club’s books, erasing a big chunk of its deficit at a time. Selling Salah was a wrench. He combined for 26 goals (scored 15, set up 11) in Serie A in the final season of his 18 months in the Italian capital, second only to Jose Callejon of Napoli. He had quickly become a fans’ favourite. The then Roma coach, Luciano Spalletti, had helped develop Salah’s all-around game so he was more than just a speedy winger, but an efficient and creative one, too. As it turned out, $50 million was a bargain.
