Virgil van Dijk has questioned the need to play four Nations League games at the end of what has been a relentless season.
Europe's top players especially have endured mammoth workloads, and few have been called upon more than the Liverpool centre-half. The Dutchman was integral to the Reds' push for the quadruple, which eventually fell short following near misses in the Premier League and Champions League.
That said, Liverpool's success meant they played in every possible game this term having won in the finals of both domestic cups. Van Dijk himself played in 51 games and is now gearing up for international duty less than a week after the European Cup final in Paris.
