(Reuters) -England skipper Harry Kane has hit out at several players who withdrew from the national team ahead of their Nations League matches against Greece and Ireland, saying on Wednesday that country must always come before club football.

Harry Kane says he is disappointed by the high number of withdrawals from the England squad this week, insisting the national team must come first.

What do England need to gain promotion from the Nations League and what are the permutations? And how could they also secure a World Cup play-off spot?
