The Toffees reportedly had several bids of up to £8 million rebuffed by the Scottish Premiership champions during the summer transfer window.
Adam - who now plays for Dundee after spells at Ibrox, Stoke and Liverpool among others - told the Daily Record: “A Premier League club in England made a bid for Nathan in the last window.
"That shows you they think he is a good player with the potential to play at the top division down south.
“Rangers will sell if they get the right price but the board are standing strong at the moment and are not selling, which is commendable. They want to push on in the Europa League and win the Premiership again because it guarantees them a place in the Champions League.
“You are always going to attract interest in your best players and the form that Nathan has shown in his short career has generated that. He is 19, athletic and a right-back. There is always going to be interest in that kind of player.
“He is still young and is still learning the game. He hasn't even played 20 games for Rangers yet. He has still got a lot to learn. He will know that.
“He has got a good manager and good coaching staff at Rangers who work with him every day and help him develop. He will get games there because his club play so many games domestically and in Europe.
“He will get opportunities. When he comes in he has to take the opportunity and put the pressure back on the manager to pick him. He has got a big future ahead of him.”
Patterson emerged as one of several right-backs that Everton tried to recruit during the summer transfer window.
However, Rafa Benitez's side failed to get in an additional option to provide cover and competition for Seamus Coleman.
Denzel Dumfries opted to join Inter Milan from PSV, Arsenal blocked a loan move for Ainsley Maitland-Niles and Southampton snubbed interest for Kyle Walker-Peters.
However, it's likely that the Toffees will still covet someone to fill the void when the January window opens.
Coleman’s current hamstring injury has hammered home how an additional option is needed.
Ben Godfrey has played as a makeshift full-back in the Everton captain's absence, with recognised right-back Jonjoe Kenny being overlooked.
