The Reds remain in the driving seat in their group, but Keane admits they still have a lot of work left to do.
The former Spurs striker said: “We’ve got to be happy with where we are in the group because we’ve played three games, two of which have been away from home, and we’ve taken seven points.
“We knew that Madrid would be a tough place to come to because Atletico are a good side but we’ve managed to take a point which is definitely a good result.
“But there’s still work to be done. We know that and we have to focus now on the next game and not start thinking too far ahead.
“It’s always nice to score but it would have been even nicer if we’d managed to take the three points.
“Unfortunately, that wasn’t to be, but all in all we’ve got to be happy with a point because I suppose it could have gone either way.
“This is a great competition to be involved in and hopefully there’s still a lot more games to come for us.
“We can’t allow ourselves to become complacent or get too carried away. But, at the same time, we can be confident that we will go on to qualify.”
