Jonathan Barnett believes Madrid fans would be wise to remember as much, with Bale having contributed significantly to the success of the club in recent seasons.
The Wales international has faced plenty of criticism in the Spanish capital this season, but he will not be running away from the Santiago Bernabeu
He believes those efforts are being unfairly overlooked during a testing campaign for all concerned, with one of the finest players on the planet becoming a scapegoat for those who should be grateful for his presence.
Barnett told Sky Sports: “This generation of Real fans will be talking about Gareth’s goals for years to come. Frankly, they should be ashamed of themselves.
“Gareth deserves the greatest of respect. The way Real fans have treated him is nothing short of a disgrace.”
Bale was jeered from the field on his most recent outing for Madrid.
He was drafted back into Santiago Solari’s starting line-up for a Clasico clash with Barcelona on Saturday, but lasted just 61 minutes.
Real were already trailing 1-0 when he was replaced by Marco Asensio and would go on to suffer defeat by that scoreline to their arch-rivals.
Bale contributed little while on the pitch, but the same could be said for many of those around him.
He has contributed 15 goals to the Madrid cause this season, including a hat-trick against Kashima Antlers during another successful Club World Cup campaign.
His outings have taken him past 100 strikes for the club, and 200 appearances, but intense speculation continues to surround his future amid talk of a possible Premier League return this summer for the former Tottenham man.
Barnett has moved on a regular basis to quash such talk, but his latest comments are likely to have done little to dampen the exit speculation in Spain.
