Liverpool defender Sami Hyypia knows Djibril Cisse will be out to prove critics wrong when he visits with Olympique Marseille tomorrow night.
"We have to stop him from doing that."
Things did not work out for Cisse - the Reds' then record £14million signing who suffered two leg breaks - under Rafael Benitez and he went to Marseille on loan before being signed for £6m in July.
But Hyppia added: "He can score from everywhere, he has a powerful shot and is lightning quick, so we will have to be on our guard."
