Defender debuts in Spurs defeat
The 27-year-old made his Club debut in the contest, but couldn't prevent Alex Neil's men from being seen off by Spurs in convincing fashion courtesy of Dele Alli's early strike and two goals from Harry Kane.
Speaking to Norwich City TV after the game, the defender said: "We're very disappointed because we conceded goals too easily.
"That's what killed us today, even though we were good at points in the second half. You go into the match with a game-plan and going down 1-0 early on changed things.
"It gave them the chance to play how they wanted to, which made things hard for us. They pressed high and gave us very little time on the ball.
"I'm not completely happy with my performance, and I know I have things to work on in order to reach the next level."
City's next match sees them travel to basement club Aston Villa on Saturday, looking to arrest a run of four consecutive league defeats.
However, Klose believes his side are capable of making a return to form, and added: "There's a lot of quality in our team and I'm confident we can produce a good performance.
"We have to be prepared because it's an important game. There's going to be pressure, that's for sure, but as football players it's our job to go there and fight.
"If we want to stay in the league we have to win games like this, or at least not lose them."
