Wales international forward Roberts has come to the end of his third full season at Leeds and is now heading to the European Championships with his country.
Leeds signed Roberts on a four-and-a-half-year deal from West Brom in January 2018 and the 22-year-old has opened up on his happiness at the club and says talks about his future are ongoing.
Roberts has seen Leeds transformed from a mid-table Championship side to a team who finished ninth in the 2020-21 Premier League season after being improved out of all recognition by head coach Marcelo Bielsa and by some flash new signings.
Brazilian winger Raphinha has been the flashiest of the lot and Roberts has been hugely impressed with the player signed for a snip at £17m from Rennes last summer.
"Baller, he is a baller," Roberts told The Beautiful Game Podcast, asked specifically about Raphinha.
"He is different with it. He's not just a game day player.
"He's a player that I really like because apart from being Brazilian and having that flair, his work rate is ridiculous.
"He's one of them people where say we are doing a shooting practice and everyone is just having a laugh and that, if he misses one or gets the technique wrong, he is angry at himself.
"You know he has got them in where he pushes himself as in every time he has got to be hitting it properly.
"Some of the stuff he has been doing is just outrageous.
"He's Brazilian, he just enjoys playing football.
"It doesn't matter where he is, he just enjoys playing football."
Raphinha missed the start of the Premier League season having only joined Leeds from Rennes at the start of October,
The Brazilian finished the campaign with six goals and nine assists.
Asked if he knew how good Raphinha would be from training, Roberts said: "Straight away.
"Murderball sessions, it's long.
"He's just running everywhere, getting on the ball, just going past people.
"He is just a joy to be around and watch as well.
"He doesn't speak too much English but we do speak a little bit and he's a good vibe. He's great."
Reflecting on his own future - and asked if there had been any talks about adding a couple more years on to his contract at Leeds, Roberts revealed: "I think my agent has had a talk with them about what is going to happen in the future and stuff.
"I think it's all positive and I do love it at Leeds - the city, the fans and the experiences that I am getting are great so I'm happy."
