"I think we did a good game," Lage said. "I think we were the better team, we created a lot of chances, and we didn't score. I'm happy with the performance, but not happy with the result.
"I said before the game that we came here with big confidence, and we'll score goals because the pre-season was good and we have confidence to play in this system. I was right to feel that confidence, and we continued to play."
He added: "It's time to be patient because we are talking with players. I know the club are talking with players and those players can come and increase the level of the team and the squad.
"They will give solutions that we didn't have today."
