The former Wolves striker was speaking after their FA Cup third-round win over Liverpool and had this to say about Nuno's efforts this season.
The Portuguese coach hit the ground running following his switch from Porto to Wolves ahead of the 2017-18 campaign, leading the Molineux side to the Championship title in his first season in charge.
Wanderers topped the table in style, finishing on 99 points with 82 goals scored and a goal difference of +43, testament to their swashbuckling style, but Nuno would have been forgiven had he opted to switch to a more pragmatic style in the top flight.
However, he has stuck to his guns and to great effect, with Wolves safely mid-table as of mid-January and into the fourth round of the FA Cup thanks to their superb 2-1 win over Liverpool on Monday night.
Keane was at Molineux to watch the game between two of his former sides, the Irishman having come through the ranks at Wolves and scoring 29 goals for them between 1997 and 1999, according to Soccerbase.
He spoke to the official club website about what he thought of Nuno's efforts so far this season, and suffice to say, he seemed very much impressed.
"The great thing about the manager is he hasn’t changed his philosophy," said Keane. “He’s stuck to his principles and played the same way, and the players have repaid him. He’s giving the players the opportunity to play in the best league in the world and they’re doing a great job.”
