Currently Lewandowski leads the goal tally with 14 goals he has scored, 2 times more than other players below him who have 7 goals. Clearly this is a good thing that he can give and also do not forget that this can happen because he does get support from his teammates who also played very well this season. Hansi Flick can understand what he is implementing, I mean he understands the abilities of his players which makes him able to play well like this. Indeed, the role of the coach is very important, especially in understanding each character of the player, because that way the strategy that will be used can run very well.
It's big difference in about one-third of season but it is too early to call him as a best scorer of La Liga in this season. The bigger challenge for Lewandowski to win this award, is himself, his body and injury or not in rest of this season. If he can avoid injuries, he will have more appearances for Barcelona and with a very good team like they've shown so far, Lewandowski will receive many good key passes, assists for scoring more goals.
It's not coincidence that Lewandowski is a third best goal scorer of all time in Europe's top leagues.

Not expecting all that to happen, but in football it can happen and not only from his own factors, maybe Barcelona will also experience a decline and that will affect the players. But at least with what he shows now, it makes his confidence grow even more, especially with the promising game that Barcelona has managed to show. Now their job is to maintain the good performance they are showing now.
