He was no stranger to a long-range screamer during his own playing career, but Rangers boss Steven Gerrard insists Kemar Roofe's strike from the halfway line is the best he's EVER seen.

The striker came off the bench in Belgium to put the seal on a fantastic Europa League win, shrugging off two men before firing home from 55 yards.

And his manager paid the striker the highest of compliments as he said he'd never seen anything quite like it.

Gerrard raved: "The goal was a moment of genius, it was a world class moment.

"I've been playing football professionally since 1998 and it's the best goal I've ever seen live with my own eyes.

"He collects the ball 15 yards outside our box, he is strong for two challenges, he holds the player off with the third challenge and then he actually takes the player on in the worst conditions I've seen.

"Then to have the vision and the power and the class to score from 55 yards - I don't think I've seen a better goal and I don't think I will see a better goal.

"It's a very important victory to start the group in a positive way."

The win was Gerrard's first away from home in the Europa League group stage and he feels his side took a big scalp: "We've beaten a good team tonight, we deserved the victory.

"We were good defensively in the first half besides one moment from a cross, with the header that hit the crossbar.

"But in possession we needed to improve, we needed to be better.

"Second half we were outstanding for 20 minutes and then the game changed with the weather, it was very unpredictable it was difficult for both teams.

"But we managed the game extremely well and we take three important points away.

"It's in your mind that the officials might delay and take the teams off.

"I'm happy that he decided to play on, obviously, but the conditions for both teams and every player were very unpredictable, they were very difficult to control.

"Moving the ball, passing the ball - everything was very difficult.

"The rain was incredible, the thunder. I think for the last 20 to 25 minutes it was about which team wanted the victory the most.

"We had one scary moment at the very end, thankfully Standard didn't score because it might have changed the game.

"Second half I'm very proud of my team, we were much better and we deserved the victory.

"We had two or three other really good chances to score, so I think that's important for the next time we play Liege - we know we're capable of creating big chances."

Roofe and Ianis Hagi have both played in Belgium, and gave their manager some key information about Standard before the match.

However, the striker was involved in an altercation with the Belgian squad after the final whistle.

Gerrard said: "We got really important information about key individual players.

"They helped me to get to know the Standard Liege players better.

"The record that Liege have here, six years undefeated, you can see why because they're a strong team with good players.

"The manager plays in a good, aggressive style.

"So I'm really happy for my players, it's a big victory, and it's a shame at the end.

"Kemar gets a yellow card for the incident, that's for me to speak to Kemar and deal with that situation.

"The reaction from Standard was disappointing but we forget it and we move on."
