Yeap. The squad is good enough for him, including the fourth and fifth players to cover the front three. And obviously Klopp is crazy, to some people (not you) for not strengthening at this "opportune" time, which is a "lost opportunity". But yes, we can all understand why. More exciting, but without proof as he says... He has an analyst looking at the stats and what players can deliver vs the market price. That is his proof. While we all base our views on gut feel. Unless those couple of us have the same database...
Jürgen Klopp exclusive interview: Liverpool's transfer window explained and title race assessed
"You should never do transfers because other clubs are doing transfers. That makes no sense, it's not about that. And if you sit back for a second and have a look at the squad, do we need more players? People will say, yes, we need a substitute for Sadio Mane, for Mohamed Salah, whatever.
"But those players are here. So, do you get a one-for-one replacement? A big signing? People think that players from other clubs, other countries, are better than the players we have here but without really having the proof, because those players haven't played here, or whatever else.
"It's just that what is new is seen as more exciting. It's like with a new car. Your old car is completely reliable, but you want a new one and two weeks later it breaks down. It looks better, but obviously it's not that good."
