A lot has been made recently of who the signing of the summer was in the Premier League, but there can be no doubting now that it was Mohamed Salah.Signed from AS Roma for £34.3 million, the Egyptian has been sensational for Liverpool and made Chelsea look rather silly for getting rid of him last year.Heading into Saturday's game against Southampton, Salah had scored 12 goals in 17 appearances in all competitions for the Reds.But Jurgen Klopp insisted the 25-year-old was capable of even better, saying: "He could have scored even more. He's a fantastic player and can still improve."It turns out Klopp wasn't wrong. Salah struck twice at Anfield on Saturday to hand Liverpool all three points in a convincing 3-0 win.His 31st-minute opener was an absolute peach, cutting inside and curling the ball past Fraser Forster from just outside the 18-yeard box.And ten minutes later Salah bagged a brace to take his overall goals tally for the season to 14 and give Liverpool a 2-0 lead.Philippe Coutinho made it three after half-time but Liverpool fans just couldn't stop raving about Salah, who is making a mockery of his transfer fee.Even club legend John Arne Riise was going crazy on Twitter and his tweet just about summed up how everyone at Liverpool is feeling about Salah right now.

RIISE IS LOVING SALAH

He wrote: "Excuse me Mr Salah, but what are you made of? What a player we have!"

Like most Liverpool fans, Riise can't believe how good Salah is and he's clearly very excited by what the future holds.

As you can imagine, the former left-back received all kinds of responses, such as: "He's made of lightning," and, "Egyptian Gold." Here's how Twitter reacted.
