Polish football fans had expected their national team to reach the knockout stage of the FIFA World Cup in Russia but the squad "failed to show their strength," according to former Spartak Moscow and Poland goalkeeper Wojciech Kowalewski.
Poland were knocked out of the World Cup after suffering a 3-0 defeat at the hands of Colombia on Sunday and will face Group H leaders Japan in their last game at the tournament in Volgograd on Thursday.
"We will have a very difficult game with Japan, we need to win in order to take leave of the World Cup on a somewhat positive note," said Kowalewski.
"Everyone in Poland said that the group was difficult, but they expected the team to advance to the knockout stage. It's a pity that they didn't get past the group stage, Adam Nawalka has a good selection of footballers, but they failed to show their strength," he added.
The 2018 FIFA World Cup kicked off on June 14 and will continue until July 15, with the matches being played in 11 cities across Russia.
