In our final 2018 FIFA World Cup group stage preview, we feature Group H, in which Poland and Senegal's final 23-man squads made the headlines.
Click through the gallery to see three Poland and three Senegal stars one might want to keep a close eye on during this World Cup.
Group H kicks off on Tuesday, with Colombia taking on Japan at 14:00, and Poland and Senegal set to lock horns at 17:00.
Poland were impressive at the 2016 European Championship, and were unlucky to lose on penalties to eventual winners Portugal in the quarter-finals. The Poles have travelled to Russia with a similar squad to their Euro campaign, and will be relying on Robert Lewandowski to fire them as far as possible.
Four years ago, Colombia were one of the standout performers at the 2014 World Cup, with James Rodriguez in particular making a name for himself, and this time around many feel they could be a dark horse in Russia.
Senegal shocked the world by beating world champions France in the inaugural match of the tournament 16 years ago, before reaching the quarter-finals, and many feel the Lions of Teranga are Africa's best hope of making it to the knockout stage.
First round of fixtures:
19 June, 14:00 – Colombia vs Japan, Mordovia Arena
