Shaqiri completed the scoring in breathtaking fashion in MI, where Liverpool ended their International Champions Cup campaign with a resounding victory Saturday.
"The atmosphere was good, but if I was them I wouldn't come".
The teams weren't at full strength, but the crowd of 101,254 didn't seem to mind too much.
Sadio Mane converted a penalty to open the scoring for Liverpool in the 28th minute.
The young Brazilian bent the ball up and over the wall into the top corner, leaving Liverpool's young goalkeeper Kamil Grabara in no man's land. The Reds, then managed by Louis Van Gaal, initially fell behind courtesy of a Steven Gerrard spot-kick, but fought back with goals from Wayne Rooney, Juan Mata and Jesse Lingard to win 3-1 and claim the pre-season trophy.
Shaqiri, of Switzerland, was one of five recent high-profile signings which saw Liverpool shell out more than £200 million ($260 million) in an attempt to close the gap on Premier League champions Manchester City.
"So I would suggest that Liverpool would be second this year, it's possible they could be first, but I'm going to say second".
"The only real story I know from MI is the Fab Five", Klopp said.
Fred, Nemanja Matic and Paul Pogba are without a doubt Mourinho's first choice midfield and it's clearly one that's hard to get into. I think it was a week after he finished the World Cup, so I said: 'No, no, no. Go!'
