Jordan Henderson says Daniel Sturridge’s return to the Liverpool team has brought back the fear factor in the side.
The England international, whose season has been plighted by injuries, started his first Premier League game since October in their 6-0 triumph over Aston Villa on Sunday, with Sturridge scoring the first goal in the 16th minute.
However, Henderson is convinced Liverpool's fear factor is back and if Sturridge stays fit he'll become world class.
"[Sturridge] makes a huge difference," said the Reds captain, as the Daily Telegraph reported. "You can see in the games that he has played how much he has been missed.
"He has been brilliant since he has come back to training and is looking really sharp. Hopefully he can continue to stay fit and cause problems when he plays.
"Everyone knows how good he is but because he has been out for a while, you do forget the quality he has got and how good he actually is.
"There are lads in training who maybe haven't seen that much of him and they have been very impressed. Then you look at him in the games with his movement. His sharpness is top drawer. He is a massive bonus for us.
Henderson added: "He definitely gives us that fear factor back. Any central defender playing against him will be wary. They know how quick he is, how sharp he is with the ball.
"He can cause anyone problems and I'm sure any centre-half in the world would be worried about coming up against him.
"He's definitely one of the best. When he is firing, he is one of the best in the world, reallysaid.
"He is that good. Finishing, touches, movement - he has got everything. He gets one chance and scores one goal and that is the difference.
"His biggest problem is getting a run of games, finding consistency and just staying fit. That is the only issue. If he stays fit, he becomes world class."
