Liverpool defender Virgil van Dijk believes players are at a greater risk of injury after UEFA scheduled four Nations League games to be played this month.
Van Dijk is part of the Holland squad that plays in Belgium on Friday evening and then travels to Wales for a game on Wednesday before home matches against Poland and Wales in the competition the following week.
The Reds centre-back has played 59 games for club and country since returning last summer after nine months out with an ACL injury.
