Manchester City manager Pep Guardiola believes some competitions in English football must be scrapped to protect the welfare of players and increase the quality of matches.
City face Sheffield United away on Tuesday night in the Premier League in their 17th match in 59 days since the last international break in November.
Serious injuries to Tottenham's Harry Kane and Manchester United forward Marcus Rashford that could have an impact on England's chances at Euro 2020 have highlighted the issue and Guardiola believes the status quo is "unsustainable".
"The players arrive at the Euros, trying their best with their national teams then they are back here after no more than 20 days' rest because the show must go on. It's unsustainable,"
"They (the Premier League) should reflect on it but all the managers complained about it and they don't care."
"Less games, less competitions, less teams, less quantity and more quality."
