What I will say will be hugely disagreed with, but it's my practical experience from over a decade of building teams and developing players, saving teams from relegation and winning trophies. I'm not giving an opinion, I'm making an observation based on practical experience -
When you go into games focusing on "winning" them, you end up with performances like that one - stilted, rushed, forced, high intensity but low-intelligence; random, sloppy, and lacking in real tempo or rhythm. In those games, we seem to have had the mentality of "we must win".
When you go into games focusing on "playing your football" (whatever your "football" is composed of), you will end up winning more, because you will make better decisions, better use of space, better use of the principles of play, play with the right tempo, the right energy, and the right composure on the ball. And so your plan, if it is superior, should lead to a win, at least 50% of the time (standard across all team sports). If you have a superior plan and superior players, you might skew that standard a little past 50%. If your plan is off, or you don't have superior players, it might dip a little below. Either way, though, you give yourself a better chance of winning by focusing on the way you play (whichever way that is - it might be possession, it might be attacking, it might be defensive; it might be the same formation and shape, or it might be a different one each game to combat the opposition - it doesn't matter what your "game" is, as long as you focus on executing it).
Today, and last week, we seemed to focus more on getting the result, and our final ball became sloppy, and our shape narrow, and our execution poor. Before, when we were scoring regularly, we would be focused on our possession game, because it was new and the players had to. As a result, we could take teams apart from the lower half of the table, because we had the superior players, principles, and shape. As long as we go into a game chasing the win, we will abandon the things that make us good. This is something that both management and players would be culpable for. It is counterintuitive, but that that is how things are. It's the reason why , Rafa, Mourinho and Ferguson have been so successful - they focus on what they can control, and making sure their players stick to the principles. If you want to see a good example of it, there is a Chelsea documentary from Mourinho's first season where they are preparing for the game against Bolton that would win them the league. He is very adamant at the end about not focusing on winning. He says "there is no pressure to win. I can't ask you to do that. But we must not lose". The end result from the players is that they have no pressure on them to do anything more than play their own game and trust it to get the result. This is something that both the players and the manager should take heed of, although it's hard to tell without being in the team-talks what is being said and who is emphasising what aspect.
