Virgil van Dijk admits Liverpool will get thumped in the Community Shield if they repeat their performance against Napoli.
The Reds were blown away at Murrayfield as Carlo Ancelotti's side secured a 3-0 victory.
And Van Dijk knows a similar display against Manchester City this weekend will end poorly for Liverpool.
"Yeah, definitely," he said when asked about its importance. "Last year we had a very tough camp over there. There was a lot of hard work and also a lot of tactical work as well. I expect a little bit of the same.
"Obviously our season starts properly on Sunday, so this week will make sure our heads are together and focused on City."
