Derek McInnes insists Ryan Jack will make a huge improvement to the Rangers midfield when he returns from injury.
The Scotland international has been missing since February with a calf problem that needed surgery to sort out but stepped up his return last week.
Steven Gerrard has good options in the middle of the park but is a huge fan of Jack and his former Aberdeen gaffer reckons he'll slot back in to being a key player.
The lengthy injury has been frustrating for Jack and Gerrard as well as the Rangers support but McInnes believes he'll get back to his best in no time.
He told the Daily Record: “I think Ryan, through his performances over the last year or two, has shown most Rangers fans and certainly the manager that he is such a key player for them.
“Even more so, this season, when he hasn’t played you can see how much he has been missed.
“When he is available, it does allow Rangers to maybe use Steven Davis a wee bit more strategically to keep him fresh because both players are very similar in how they play the game. They are like a metronome in the middle of the pitch and they are everybody’s first pass in the team.
“For me, Ryan makes every team he plays in better. He made my Aberdeen team better. He makes Rangers better when he plays and he makes Scotland better.
“He is a top, top player and hasn’t had his troubles to seek with injury. This latest injury has taken a bit longer to clear up than he’d have hoped."
