The goalkeeper has also vowed to do all he can to help the youngster settle at Anfield.
The striker sealed a move to Anfield last summer after an impressive World Cup with Belgium, but spent the 2014/15 campaign on loan at French side Lille instead of joining straight away.
He had a somewhat indifferent campaign in France though, scoring nine goals in 37 games in all competitions. Nevertheless, there is big expectation waiting for him in England, and Mignolet believes he has all the qualities required to be a hit.
"He's got a lot of ability,” he said.
“He is quick and can score a goal and he is willing to work for the team and put pressure on defences. He's got a great attitude, so what more do you want? I am looking forward to when he is going to join."
With Liverpool’s forwards having failed to hit the heights of the season before last year, there is naturally a level of hope that the Belgian will come in and hit the ground running for Brendan Rodgers’ side.
However, it is likely to be a steep learning curve for the 20-year-old, who will not only have to settle into the rigours of the Premier League, but also the difficulties off the pitch as well as he moves to a new country.
Mignolet, though, has promised to help in any way he can, while he is also enthused to have a fellow compatriot in the dressing room with him.
"I'm always ready to do that with anyone who comes into the team, and obviously being Belgian it should help Divock,” he added.
"It's nice for me, too, to have a compatriot coming into the team. It means that I won't be the only Belgian anymore so it will be easier for me to fight my corner!"
