Poland 0 - 3 Colombia. Is it the end of Lewandowski's and Glik's era in Polish national team?

Match in Kazan shown us - fans of Polish National Team where is our REAL place in "the football world". It is far below the FIFA TOP 10 chart. Strange FIFA rank system placed us where we have never( I mean last 30 years - whole my life, so far) belonged and now there is a big disappointment all over the country. We have our expectations despite the Tuesday's loss against Senegal and I think it was like "living in a dream". To be honest today was the day when that FIRST loss made me angry and sad again. Colombia was considered as the strongest in group F and, despite of it failure against Japan, and it still is, so the result and playing style of Nawałka's team wasn't that thing which has thrown Pland out from the tournament...It was the playing style and the result against Senegal...
In 2002 we have lost against South Korea 0-2 in first match, in 2006 the same result against Ecuador and this year in Russia...that "great game" against Lions of Teranga ended with shameful 1-2...That was the match within we wasted our chance to do something more than 3 games in World Cup 2018.
Lewandowski was alone, then on Tuesday and yesterday (on Sunday), against two(always) or three (often) Colombian or Senegalese defenders. It was too much even for RL9 and surely it was Adam Nawałka's mistake to put whole responsibility on Lewandowki's shoulders. We know about Robert's problems in Bayern (conflict with part of the team and his will to leave Bayern despite of chairman statement). Polish striker had recently some problems with scoring goals and that should be also signal for polish national team coach to find ANY support but...there was none.
Regarding Polish defensive play: our dramma started few weeks before 1st match in Russia: during one of the training sessions Glik has fallen on his shoulder and that was the beginning of Poland's catastrophy in defence. We have lost true leader (right after Lewandowski) and it seemed to be our "curse" through the first and second game - We have conceded FIVE GOALS so there was no chance to get even one point with offensive indolence.
Probably because of two "indisposition's" whole game plan have gone wrong...Now there is one game left and coming back home... I think it is the last game in national team for both mentioned earlier(in FIFA WC Tournament)and I hope we will find theirs successors sooner than later... Otherwise we will wait for other Poland's World Cup apperance another 12-16 years...
