Skrtel says Liverpool are now free to focus on the Premier League.
He told his official website: "We were really unlucky and I'm disappointed.
"I think we played really well and maybe we could say we were even better, but the result is all that counts.
"We had some really good chances to score but we didn't convert them and this is the result.
"Now we must be fully focused on the Premier League and I really hope we can do something very positive there."
