The Reds snatched all three points as they were awarded a stoppage time penalty after Dominic Solanke was barged over in the area and Mane - who was introduced at half-time - made no mistake from the spot to seal a 2-1 victory.
Salah, Mane and Georginio Wijnaldum only joined up with Jurgen Klopp's side in NY and the Egyptian forward, a 62nd-minute substitute, again stood out, picking up where he left off last season when he headed Rafael Camacho's cross past Joe Hart.
Asked about Salah's return post-match, Liverpool manager Klopp told reporters: "I said before the game, it's not that he has problems - he has no problems". "I don't know what I'll do but I couldn't play for another English side".
"He came in and scored after pretty much 35 seconds". Both centre-halves were there. He has the talent to do that and we are happy that he scored. We need to keep improving as a side with him as well, and make sure that all the pressure is not on his shoulders to deliver goals and get us out of tough situations.
The first half was a dour affair but the ICC clash came to life after the break following the introductions of Salah and Mane as Liverpool bounced back from their 3-1 loss to Borussia Dortmund. Ever since winning the Premier League with Leicester, he was ready to move on.

Meanwhile, despite playing with mainly reserves in the first stanza, Mahrez displayed his creativity and pace on several occasions for Man City. We won against City, what does that mean? The game for us was very important, but it is not a sign in the direction or whatever.
The Reds' starts and finishes have been too poor for a side looking to challenge for the Premier League title, as they've either started the season looking seriously unprepared or ended it blowing hot and cold.
