Those are the thoughts of legendary Liverpool winger John Barnes.
Salah joined the Reds from Roma last summer for a then club-record fee of £36.7million.
The Egyptian has had a stunning debut campaign, scoring 30 goals in all competitions.
Barnes is a huge fan of Salah and his fellow attackers Sadio Mane and Roberto Firmino, claiming they are the best forward-line he has seen at the club.
But he does not think Salah would be as good at Manchester United and says Liverpool boss Jurgen Klopp is a huge reason for his successful start at Anfield.
“I think they are (the best), but for me I think it’s mostly down to the manager and the way they play,” McCoist told talkSPORT.
“The way Liverpool play suits a front-three like that.
“I don’t think Salah would do as well playing in a Man United team because of the way Mourinho sets him team up.
“I think you are a reflection of how the manager wants you to play.
“I think the front-three have a lot to be grateful for, for having a manager like Jurgen Klopp.
“Liverpool are bearing the fruit of the trust they have put in Klopp, because the team is starting have the right balance, that will only get better when Naby Keita comes in in the summer.”
Salah played under Mourinho at Chelsea but was sent out on loan twice, failing to gain a regular spot under the Portuguese.
