Glen Johnson believes new Liverpool teammate Daniel Sturridge has the ability to 'petrify' defenders and open up space for others to capitalise on.

The Reds full-back has been highly impressed by the 23-year-old since he switched to Anfield last month, and echoed the view that Sturridge can combine with Luis Suarez to great success.

"Danny Sturridge has ­settled in well and I think he'll do some fantastic things here at the club," enthused the 28-year-old.

"He will be a fantastic signing. He will petrify defenders because he's so sharp, quick and unpredictable at times.

"He will always occupy at least two defenders, which gives the rest of us ­opportunities to make runs around him.

"He will be a great asset for us. I know how Danny felt at City and Chelsea.

"Every player wants to play in every game.

"I'm sure Danny left ­Chelsea to get games and show what he can do ­because he's a fantastic player.

"It's a great challenge to go up against Danny and Luis in training. I can really see the partnership being very good for us.

"We've already seen that, but it's still early days and it's going to improve over time as well. It's looking bright ­between them."

The Reds have entered a crucial period in their 2012-13 campaign, following up a 2-2 draw against Arsenal in midweek with a Sunday trip to face reigning champions Manchester City.

Johnson and co are currently seven points off fourth place in the Barclays Premier League and the attacking defender is confident that his team can challenge for a Champions League berth.

"The top four is still a ­realistic aim for us," he added.

"We can only worry about ourselves, but we are giving ourselves a chance and ­picking up points.

"If we can find some kind of run from now until the end of the season, I'm sure we'll be pretty close.

"There are probably six teams fighting for fourth place this season. It's very open. We know it will be tight."
