Alexander Isak makes Newcastle return! Liverpool transfer target trains alone at Magpies' HQ amid strike from first-team squad

According to The Sun, Isak looked 'crestfallen' on his return to Newcastle's headquarters in club colours this week. Meanwhile, NUFCBlog added that the on-strike 25-year-old reportedly engaged in an 'awkward' one-on-one session with an academy coach at the Magpies' Little Benton base on Wednesday.

In an explosive social media post, Isak sent shockwaves around the footballing world when he accused Newcastle of "breaking promises" amid his bid to join Liverpool. His current club responded by stating they were "disappointed" with his claims and denied there was any prior agreement that would allow him to leave the club this summer. This messy saga is still rumbling on.

The Sweden international, who still has three years left on his St James' Park contract, is reportedly due to be fined over his refusal to play against Aston Villa in their Premier League opener last weekend.

Isak, who was told to sack his agent immediately by Newcastle legend Alan Shearer, is running out of time to find a way out of Eddie Howe's team. Liverpool are yet to return with a second bid, after their only offer of £120 million ($162m) was rejected. It remains to be seen if the former Real Sociedad man will join the Reds before the transfer window shuts on September 1.
