I agree with your post directly above for the most part, but surely it's the managers job to get the players mentally prepared in the best way possible so they have composure in those moments? You can't train finishing, but you can manage mentality.
Yes i already said that
But you can hone your technique to such an extent that it becomes second nature. The less you have to think about the actual technique involved in finishing, the more natural it comes to you, the easier it becomes to cope with the mental side of it. Of course you can train and develop finishing skills. Look at Wayne Rooney. Or Dries Mertens.
Fernando Torres sure as hell did that at chelsea. He surely was good at it in practice. Come game time, he couldn't hit the side of a barn from 5 yards. The same Torres who was a goalscoring machine at Liverpool
Do you agree that shooting is an important part of finishing? If yes, your other point is invalid. Maybe shooting isn't everything, but if it's a factor in finishing, then you can practice finishing by practicing shooting. Besides, the manager also influences the mentality of his players.
You can practice finishing by practicing shooting, but if you can't cope with the pressure of those situations during games, it won't do you much good. And yes, manager's do influence the players mentality. I've said that. Right now it's mostly a confidence issue imho, 'pool players are too afraid of missing those chances. It's Klopp's job to get them in a mental frame where they won't feel like missing a chance is the end of the world. Being able to create more chances would be a big help
Lamps used to practice finishing and got himself hundreds of goals. You can practice anything, apart from being the victim of an accident.
You can practice the technical aspect, not the mental one. That involves a completely different type of training. In football like in life, confidence is everything. Some players are just naturally more confident than others. Look at Coutinho's finishing and compare it to Firmino or Salah
Different sport, entirely different thing
Except finishing is a skill that can be evaluated, and you can buy players who can finish. This is why we spent money on Lukaku.
Sure. But those same players scored 78 goals last season, those same players never had much problems scoring goals. A guy like Lukaku would have helped, sure, but then again a guy like Lukaku tends to eat the bulk of his teams goals. Liverpool's choice is to have 4 players who can score 15 each instead of one 30 goals striker. But that's besides the point(and yes, Klopp is covering himself there by diverting from the actual problem)
Still, fwiw, i said all summer that liverpool's priority should have been a great goalscorer
