The 24-year-old has trained with the [Magpies](https://www.thenorthernecho.co.uk/sport/football/newcastleunited/) all week having completed his £39m move from Aston Villa last Sunday, and Howe believes the midfielder will "add a lot to the team".
Joe Willock has also resumed training this week after his summer injury setback, further bolstering Howe's options in midfield. Willock's swift return has delighted Howe, who feared the worst when the former Arsenal man went down in pre-season.
"Jacob will be available touch wood," said Howe ahead of Monday's much-anticipated game against the Premier League champions.
"Of course we still have training sessions before the game, but he's in a good place.
"He's looked really impressive in his first couple of days. He's really good technically, very intelligent, I think he'll add a lot to the team. He has stand-out qualities."

Howe added: "Joe trained on Tuesday and Wednesday and trained really well.
"When he went down in the game \[in Korea\] I thought he was going to be out longer term, it didn't look good.
"Credit to him, he's got back fit and looking good."
With Alexander Isak still unavailable, Howe is likely to name an unchanged side against Liverpool, which means new signing Malick Thiaw will again have to settle for a place on the bench alongside Sven Botman.
Jamaal Lascelles is also available again, but, alongside Thiaw and Botman, will have to be patient if Dan Burn and Fabian Schar continue to perform as they did in the opening day draw at Villa Park.
Howe said: "Fabian and Dan were excellent against Aston Villa. Defending, leading, organising - making sure that we concentrated throughout the game, it would have been very easy for one slip to cost us. I thought we looked really good in that respect.
"Sven, Malick and Jamaal are all outstanding players individually and will give us a lot this year but when you're not in the team you have to be patient, train really well so when you do get your opportunity you can grab it."
Looking ahead to Monday night, Howe said: "The first home game is always going to be electric. Under the lights, evening games are always really special for us.
"I have no doubt this will be a really passionate display from the home support. We need to use that - but not be reckless with it. We've got to concentrate and deliver our game plan, but using the energy from the crowd will be vital for us."
