NEWCASTLE striker Alexander Isak was told to report for training today after the rest of the squad had left as uncertainty over his future continues.

The 25-year-old Sweden international did not travel with his team-mates on their pre-season trip to Singapore and South Korea, ostensibly because of a minor thigh injury, after Liverpool, who subsequently tabled a bid for him, let it be known they remained interested in acquiring his services.

Isak, who later informed the club he wanted to explore his options this summer, instead flew to Spain to train at former club Real Sociedad and returned to Tyneside at the weekend, shortly before head coach Eddie Howe and his squad landed back from Seoul and were given two days off.

The players were back at the training ground this morning and their families were invited to join them after training.

However, the PA news agency understands Isak, who reported back to the club’s Benton base on Monday, was told not to come in until after they had left.

The frontman has been a huge hit since his arrival from Sociedad during the summer of 2022 and played a key role last season as they ended their 70-year wait for a major domestic trophy with the League Cup and qualified for the Champions League for the second time in three seasons.

However questioned about his absence in South Korea, Howe signalled that his actions might have repercussions.

The 47-year-old told reporters: “You have to earn the right to train with us. We are Newcastle United.

“The player has a responsibility here to be part of a team and part of a squad – you have to act in the right way. So that is also at play here.

“We will make sure that any player earns the right to train with the group. No player can expect to act poorly and train with the group as normal.”

Isak is understood to have undergone treatment and light training at a deserted training ground on Monday and it remains to be seen whether he will have any involvement in the club’s pre-season fixtures against Espanyol and Atletico Madrid this weekend.

The striker faces clear-the-air talks with Howe, with his situation becoming seemingly more complicated by the day as a difficult transfer window threatens to spiral further out of control.

Newcastle tabled an improved club record bid for RB Leipzig’s Benjamin Sesko on Monday in an effort to beat Manchester United to the punch, but developments since suggest the 22-year-old is more likely to head for Old Trafford than St James’ Park.

That would represent the latest blow in a transfer window which has already seen the Magpies miss out on major targets Dean Huijsen, Bryan Mbeumo, Hugo Ekitike, Joao Pedro, James Trafford and Liam Delap.

They have managed to recruit Nottingham Forest wide man Anthony Elanga and, on loan, Southampton goalkeeper Aaron Ramsdale, but with frontman Callum Wilson and midfielder Sean Longstaff having left, there is significant work to be done, with the start of the new season just 10 days away.

Howe was already looking for a striker before the Isak situation came to a head and, with three years remaining on the Swede’s current deal – he has so far resisted the club’s overtures to sign a new contract – there seems to be little prospect of the club allowing him to leave either before they have secured a replacement or for much less than their valuation, having already rebuffed Liverpool’s initial approach.

Meanwhile, sources on Tyneside have played down suggestions that Newcastle have tabled a bid for AC Milan defender Malick Thiaw, but it is understood they are maintaining an interest in the Germany international.
