Mullins said: "Very good performance, did it the hard way from the front.
"He settled lovely in front, jumped well in front and had enough left for a kick at the end. He's mature as well and looking at him, I think he's going to make into a nice chaser, he's a fine, big specimen of a horse. He was very green the first day he ran but he's learning all the time."
Mullins is also hopeful that there's a good deal more to come from Selma De Vary, adding: "She missed a lot of time and I think she'll improve a good bit for that run, she was a little bit green going to the last; Paul brought her wide, he didn't want to get involved with the others, and I think she has a big future."
Walsh also believes there's a big future ahead for Narciso Has, commenting: "If he stays sounds he could be anything. He will make a good chaser - he jumped one of the hurdles down the back like a fence.”
Of the race itself he said: "He done all the donkey work but he quickened up the straight to the last and pulled away. All he does is gallop, but he has a turn of foot, for all I didn't want a sprint so that's why I let him go on in front.
“That was very good, certainly different to the first time I rode him. He quickened up the straight after the last and did it well.
“The way he won the last day gave me a lot of encouragement and I've ridden him out a few times at home and at home he's felt a different horse since his first run."
On the going, he added: "It's a lot heavier than yesterday, it's tough work."
