Willem van der Ark believes it would be a step down for Derek McInnes to take the Rangers job.
The Ibrox club are expected to approach Aberdeen this week to enquire about making McInnes their next boss.
But Dons legend van der Ark, who won the League Cup and Scottish Cup during his three-year stint at Pittodrie from 1989 to 1992, does not think McInnes would be wise to move to Govan.
The Dutchman said: “Derek is one of the candidates for Rangers, Frank De Boer is another who the people of Holland know well. “I think it will be a pity if Derek leaves Aberdeen because he is doing well. “You want him to stay and I think it is better for Aberdeen if he stays.
“He’s been there for over four years and maybe he wants a change. “But at this moment I don’t think it is an improvement for Derek to go to Rangers because Aberdeen are still better at the moment.”
A tall striker in his day van der Ark, 53, became a cult hero while in the Granite City under the management of Alex Smith and Jocky Scott.
He played an influential part in the Dons capturing the League Cup in October 1989 when Aberdeen beat Rangers 2-1 at Hampden.
The 6ft 5in attacker was also instrumental in the Reds winning the Scottish Cup during the same season.
He netted a hat-trick in the 6-2 win over Partick Thistle at Firhill in the third round.
In van der Ark’s second season with Aberdeen they came within two points of winning the Premier Division but were edged out by Rangers at Ibrox on the final day of the season.
Van der Ark still follows Scottish football and the Dons’ results closely.
He has enjoyed watching their transformation under McInnes which has seen them get back to competing at the top of Scottish football, as they did in van der Ark’s day, after years in the doldrums.
He added: “It’s very good to see Aberdeen challenging for cups and sometimes for the title.
“In the years I was there we had a really good squad and we played really good football. “We had good managers at that time with Jocky Scott and Alex Smith, after I left they had a difficult period.”
While van der Ark does not want to see McInnes leave Aberdeen, he does believe they are still capable of being a force even if McInnes does decide to move on.
He said: “I think they can still be a good side. “In the years to come I think they will still do well and at least be in the first three positions. “Celtic are always consistent and they are a big club who are hard to beat for the title. “Maybe that will change in the years to come but it is all down to money. I think Rangers will do better in the years to come as well.
“But Aberdeen can still be up there.”
