David Moyes was unhappy with West Ham United's performance in a 3-2 win over Danish side Silkeborg IF in the Europa Conference League.
The Hammers held on in a nervy finish in Denmark after going ahead 3-1.
Moyes told BT Sport: "Bits and pieces I liked, bits and pieces I didn't. When it was 3-1 it should have been comfortable.
"We started making poor decisions on the counter attack, which I'm annoyed about, and a couple of poor decisions defensively.
"But look, we got the job done. Away from home, winning in Europe is not easy."
