The Spaniard suffered a hamstring injury against Fulham at Craven Cottage last weekend. Thiago will miss four to six weeks of football as a result.
But, Campbell believes that Elliott will be able to fill the void in midfield for the time being.
“You would like to think the door has opened for him now,” he told Football Insider.
“All of the substitutes that came on at the weekend looked good for Liverpool. They all made a difference to the team at a difficult stage of the game. They helped Liverpool get a point.
“Any opportunity for Harvey Elliott to get in that side and do the business is great.
“The fact that Thiago is out gives other players a chance because he would most likely have been starting every Premier League match.
“Klopp may give Elliott a chance against Palace because he is creative like Thiago.
“There is other players there who will want a chance as well though. Whoever gets the opportunity will have to take it.”
Anfield Watch Verdict
As Campbell said, Elliott was bright against Fulham at Craven Cottage last weekend. The youngster was looking to make things happen when he came on during the second half of the Premier League fixture.
However, the game finished in a 2-2 draw.
If Elliott does step in for Thiago for the foreseeable future, we are backing him to take his opportunity. Hopefully Klopp starts the midfielder against Crystal Palace at Anfield on Monday night.
