"I didn't get the chance to partner Fernando this time, but I am looking forward to it when it does happen," said Keane.
"I'm settling in just fine and it was good to get 45 minutes under my belt with my new team-mates.
"It has been a busy few days but I feel I am settling in well. I have trained a little with the lads, got in some match action and it is going fine.
"I know I did not get to play alongside Fernando but I am sure any partnership will work well, but only time will tell.
"He's a tremendous player and it will be great to play up front alongside him. But it is up to the pair of us to make it work.
"We haven't had much chance yet to work together, but over the next few weeks I am sure I will get to know him better, and the rest of the lads.
"It was useful to get the first game out of the way. I have only had a couple of 45-minute spells in build-up games with Spurs against lower-league opposition, so it was good to play against a good side like Villarreal. It was a good work-out for me.
"There is massive potential here. Just look at the players that were used in the first half, and then another fine bunch after the break.
"There are a lot of quality players here and I am just delighted to be amongst it all."
