The centre half is rumoured to be a target for the Light Blues after Mark Warburton and ex-Gers captain Davie Weir were appointed to the Ibrox dugout last week.
Wilson made his first-team debut alongside former Scotland international Weir aged just 17 and Warburton now hopes their friendship will be enough to lure him back to the Glasgow giants after rivals Celtic reportedly dropped out of the race to sign him.
Wilson was skipper of a Hearts team which reclaimed their top-flight place when they romped to the Championship title with a 21-point winning margin last term.
Alexander said: “Danny showed last year he was a level above the standard (of the Championship). He played to such a consistent level and was one of our main players.
“He was club captain as well and took that role and responsibility on his shoulders well. I’m sure whatever club he goes to, they will be lucky to have him.”
When it was put to former Rangers stopper Alexander that returning to the Championship might be a backward step for Wilson, he said: “The only person who can answer that is Danny. I’m sure he has got lots of offers from different clubs.
“Danny had a fantastic season last season and his boots will be hard to fill.
“But Danny will make a decision on his own. He’s a bright lad, a great professional and Danny will go where he thinks is best for his career.
“All this talk of Celtic and Rangers being interested in him, we expected that because we know how good he is.
“I’d like to think he will have a few more choices so I’m not sure where Danny will end up.”
