When I was supporting Dynamo Kiev in the late 1990's, I remember one episode when the great Lobanovsky was asked why he started using the tactical formation with the 2nd "libero" (a "free-role" type of centre-back, of whom Beckenbauer was a classic example). Was it intended to strengthen the defense, the journalist asked. No, replied Lobanovsky, I did it to strengthen the attack, because the 2nd "libero" can join the attack at any moment, knowing that his position is covered by the first!
This was a somewhat short-lived experiment and there might have been a hint of mischief in Lobanovsky's answer, but my point in telling this story is to emphasize that football tactics is all about balance between different parts of the team – defense, midfield and attack – and they are all interconnected, so that sometimes the best route to strengthening one part is actually changing another. We all know how a good holding midfielder can stabilize the defense or how a weak midfield can cripple the team's attacking potential because the attackers are busy fighting for the ball rather than doing their main job attacking the goal. So by the same token, a clinical striker up front can have an unexpected effect of strengthening the defense. The logic is obvious: if you're confident that your man up front doesn't need more than 1-2 chances to score a goal, then you can put more men behind the ball thus making your defense stronger. This logic is the foundation of the style of Juventus, for example – that's why they felt they needed to shell out 70M for Higuain, because having a player like him up front allows the rest of the team to play their game, being solid and attacking effectively in small numbers.
Which brings us to Liverpool FC. I think one big reason for our patchy form has been lack of speed and quality finishing up front in certain games. I don't know where we are currently in the league on chances created (shout out to
@King Binny), but a few months into the season I remember we were top by some margin. Paradoxically though, this good-looking stat may indicate something unhealthy – that we always attack in big numbers, which means by definition that we are vulnerable to the counter. Chelsea will be champions this year because they got the balance right – attacking just enough to score once or twice in every game and keeping clean sheets in most of them. Now of course there are different ways to win, but I think it's undeniable that this season we haven't quite got this balance right and that's why defensive teams have caused us problems consistently. So that's why I would say that while improving the defense and goalkeeping etc is always important, what would make by far the biggest difference against the likes of Burnley or Leicester would be having a clinical and fast striker up front. Had Sturridge recovered anything close to his 2013-14 level, I think the mood on this forum would be very different right now. Now that most of us are ready to give up on Sturridge, we need to find a new scoring machine in the summer.
