Allen returns after having been sidelined for more than a month with hamstring problem
Allen is in the squad for tomorrow’s lunchtime Premier League clash at Newcastle United having been sidelined for more than a month with a hamstring problem.
Having seen his debut season ended early by a shoulder operation, the Wales international has played only 72 minutes for Liverpool during the last seven months.
After initially impressive following his £15million arrival from Swansea City in the summer of 2012, Allen struggled for form and dropped down the central midfield pecking order.
And Rodgers said of the 23-year-old: “There's a vulnerability in every player, no matter how good they are. It's the job to manage them and give them the confidence.
“When in the Premier League with Swansea, every manager, every team we played, even the biggest ones, always mentioned Joe Allen. They said they never realised how good he was until they were up against him.
“He went into the Olympics and he was one of the top performers, then he came here, and you saw in the first three months of the season how he knitted the game for us.
“But then after the injuries sort of curtailed his form it was bit-part really. But I've never ever doubted his quality and ability. Over time he'll show that.”
Rodgers added: “He looks very good in training, the most important thing is to have him available. He's a really, really talented player, the type of player that gets underrated in this country.
“They are the bravest players for me, players who will go to within 25 yards of their own
goal to get the ball. He's a really gifted player and hopefully he'll make a real impact for us.”
Rodgers infamously referred to Allen as “the Welsh Xavi” soon after the player’s arrival at Liverpool, but the Northern Irishman does not believe such a tag has had any detrimental effect.
“He's a very clever boy, intelligent, and he's heard me talk about him like that before,” said the Liverpool manager. “I just think, as you guys who cover the patch know, that this is a special football club, when you put on the jersey it is heavier than most.
“It can take a little bit of time. Some will make an instant impact, others will be more gradual. Joe will demonstrate he's a top, top player over time.”
With Glen Johnson and Aly Cissokho also available and Daniel Agger pressing for a recall from the bench, Rodgers has a number of selection posers ahead of today’s St James’ Park encounter.
However, Liverpool will be without Iago Aspas until December after the Spanish striker suffered a torn hamstring during training yesterday.
Rodgers, meanwhile, flew to Fenway Sports Group’s Boston base during the international break for a meeting with Liverpool principal owner John Henry and chairman Tom Werner.
“It was informal, I just went more out of respect,” he said. “These are guys that come over all the time and obviously we are always busy throughout the year.
“I said I would pop over for a few days and just give them an update really in terms of where we were going, and where we were at.
“They invited me to a baseball game on the Saturday but I had to fly back. It was more just an update on where we were at.”
