Bale joined Tottenham on a season-long loan deal from Spanish and European giants Madrid in the summer transfer window.
The 31-year-old switched to the defending La Liga champions from Spurs back in the summer of 2013.
During his time at the Santiago Bernabeu, the Wales international won the La Liga twice and the Champions League on four occasions.
However, in recent years, Bale struggled to get regular playing time for Madrid and also had injury issues.
Modric played with Bale at Tottenham and Madrid, and the 36-year-old Croatia international midfielder has raved about Bale.
Sky Sports quote Modric as saying about Bale: “I have spent a lot of time with Gareth, almost all of my professional career: four years at Tottenham and seven years here. What I can say about Gareth is that he’s an amazing guy.
“He’s a little bit shy, his personality is very similar to mine. What has been said about him lately is not fair, maybe he’s judged for the last few years, but what he did in Madrid is extraordinary.
“For me he’s always going to be remembered as a player who did a lot for this team, for this club. A lot of things have been said, but Gareth never had any issue with anyone in the dressing room, he’s a wonderful guy.
“He spoke Spanish, for example, he did not give any interviews, but in the dressing room he would joke a little bit and he talked with us, and everybody was really happy with him really.
“But for sure, in the last few years a few things came up and maybe they forgot what he’s done for this club. But in a few years’ time he will be remembered as an incredible player, an important player for Real Madrid.
“Everybody has his own behaviour, and does things their own way. Gareth was like that, he would not really connect with the rest of us but I’m telling you, it was really good to have him in the changing room and I’m very sorry that everything he’s done has been forgotten in the past year.”
