The France international joined the Reds from Paris Saint-Germain for 123 million pounds at the end of the transfer window after a lengthy pursuit.
Barcola has featured five times since his arrival, starting three matches, but is still waiting for his first goal contribution. With Alexander Isak and Cody Gakpo sidelined after suffering injuries during the international break, greater responsibility could now fall on the 23-year-old.
Henry, drawing on his own experience of moving to England, believes Barcola will need time before making his mark.
“People forget that the tactic, the team and how you play matters,” Henry told Betway.
“You can see that everyone who comes into Luis Enrique’s system shines – Kvaratskhelia, Dembele, Doue, Barcola.
“It’s not always easy when you’re used to a certain system and a way of playing, where everybody knows what’s happening at any time.
“He just arrived in Liverpool, he doesn’t speak English, and it’s a different style of play with different intensity in the league.
“I had to deal with it the same way, and then that little switch happened and I was more comfortable. You start to speak English, you can joke around in the dressing room, you’re a bit less shy and people start to know what you’re about.
“It’s not an easy place to start, and he didn’t ask for his price tag, but it’s on his back.
“We all know that one-v-one, he is deadly, and he has pace. The only thing he needs to work on is his finishing, but that’s normal.
“If you see my finishing when I was 19 or 20 compared to the end of my career, it was so different. I became so much more sure about my game.
“With winning the Champions League back-to-back, playing for France, with the price tag and the quality that he has, people are not going to wait for him to become the finished article, so he’s going to have to deliver.
“There is going to be a level of expectation, and sometimes he is a bit raw in his finishing, but he creates a hell of a lot.”
