Jürgen Klopp's assertion that Adam Lallana's best years are still firmly ahead of him at Liverpool is something Gary McAllister admits he found himself agreeing with wholeheartedly.

The No.20 committed his future to the Reds on Wednesday by signing a new long-term contract, two and a half years after originally arriving on Merseyside from Southampton.

Lallana has since firmly established himself as a key component in Jürgen Klopp’s side – but McAllister agrees with the manager's view that there is more to come from the England international.

“I’m delighted for Adam, he’s an extremely hard worker and he is probably in the prime of his career - and you feel there is still more to come from him,” the Scot told Liverpoolfc.com.

“Getting this boost of the new contract is well deserved and Adam knows exactly where he will be now over the next three or four seasons, which is terrific for Liverpool.

“It would be nice if Adam could win a trophy with Liverpool because with this squad and especially the manager, getting that first trophy would lead to other great things.”

McAllister has first-hand experience of the talents Lallana possesses having worked with the 28-year-old during his spell as Liverpool’s first-team coach in 2015.

He continued: “For years I’ve always admired Adam from when he burst onto the scene at Southampton.

“He took his time to settle in here but now he is and he’s flying. It’s purely down to the manager and the system, which suits him.

“He has got so much energy and skill and that’s what you need to play in a Jürgen Klopp side. It’s all about the running power allied to being able to play quick and incisive football. That just suits his style.”

Lallana and his Liverpool teammates are currently readying themselves for the resumption of Premier League football as they prepare to travel to reigning champions Leicester City on Monday night.

The Foxes, who parted company with manager Claudio Ranieri on Thursday, are just a point off the bottom three after a season of struggle and they remain the only team in the top four divisions of English football not to register a league goal in 2017.

Nevertheless, McAllister insists the Reds cannot afford to produce anything other than a repeat of the outstanding display they turned in against Tottenham Hotspur last time out.

"We’ve just got to follow up on what I thought was a great performance against Spurs," he said.

"There’s no point winning at home and then dropping points away at Leicester so we’ve got to back it up because the race for the top four is getting harder and harder and this is a fixture we need to go and get a good result.

"Watching us against Spurs that first half was as good as I’ve seen from any side this season. We never gave Tottenham anything during the game and it really was impressive stuff.

"Sadio Mane got the two goals and looking back when we were without him at the start of the year, there’s no doubt he would be a miss for any of the top sides, any side across the globe as well because I think he’s that good. He was very influential."

McAllister played over 200 games for the Foxes between 1985 and 1990 and was a firm favourite among their supporters.

And even though his heart will staunchly remain in the red corner on Monday night, the Scot remains hopeful they can preserve their top-flight status.

He added: "I do feel a wee bit for Ranieri, who has taken a bit of flack, but sometimes players have got to stand up as well and be counted.

"I don’t think any player in the squad has replicated their form from last season, but it would be a shame if they were to go down.

"It was an amazing achievement for Leicester City to win the league, but if they were to then go down and be remembered for that would be disastrous.

"Leicester are a former team of mine, I enjoyed my time with them and I want them to stay up."

Meanwhile, McAllister also shared his pride at being named a ‘greatest ever teammate’ by Eric Cantona. The duo shared a Premier League title success in 1992 with Leeds United before the former French international moved to Manchester United.

He added: "I saw the comments from Eric. He played with some lofty company during his career in the UK, so to be seen as one of his best... well, he’s a very knowledgeable man and I’ve always said that!"
