The former Arsenal defender is yet to make his debut, despite being fully fit for some weeks.
"The playing style is not entirely new to me, but what players like Lionel Messi and Neymar show here is impressive. In particular, their commitment is unbelievable," said Vermaelen.
"Right now I feel good. I train hard.
"Luis Enrique is a trainer that rotates often. So my chance will come. Only Messi should play every minute."
