The Swiss International had limited opportunities since arriving in Stoke City in the summer.
Jurgen Klopp is famous for spending extra time with his new contract and allowing him to adapt to his style and style.
However, when Shaqiri appeared, his creativity and energy made it easy for him to believe that he was a big part of Anfield.
The 27-year-old scored a second goal 2-0 at the bottom of the Fulham table on Sunday.
Thorsten Fink managed Shaqiri in Basel in 2009-2011 and he praised the former player.
"Cristiano Ronaldo, he worked for what he got," Fink told ESPN. "But Lionel Messi, he had it.
"He did not have to work for this talent, Ronaldo has to work for this – we have to work with this body and do everything.
"For me, Messi has talent, which is for Shaqiri.
"He has this talent, and if he works very professionally, he can be the best player in Liverpool.
"You have to reach your goal every time and move on to the next level. If you do not play every week in Liverpool, it may not be enough for him.
Shaqiri was a brilliant light from Stoke, who was relegated under Mark Hughes and Paul Lambert in the Premier League last season.
But now Swiss international players are surrounded by top-notch players, and Fink has asked him to take his game to the next level.
"It is not enough to play in Stoke with his potential," he added.
"He can play in the biggest club in the world because of his talent. That's what I want.
"[He has] Everything for the perfect football player.
"The only clue is: can you make the next step, if you want to always play professional, not someone sitting on the bench every time you want to play in Xherdan? Liverpool, Real Madrid, Bayern Munich or Manchester United More expertise is needed. "
