Newcastle are set to demand close to £100million for Bruno Guimaraes, despite Arsenal initially believing he could be bought for much less.talkSPORT understands the Magpies captain has asked to leave St James’ Park to join the Gunners, who are expected to be preparing an offer in the region of £60m to secure his services.Guimaraes’ move to Arsenal hasn’t progressed as quickly as expectedShutterstock EditorialGuimaraes has been a major target for the Premier League champions during this summer transfer window.An offer of £55m for the midfielder was rebuffed in June, with Newcastle insisting at the time that they would not entertain bids for him.The North East outfit also insisted there had been no club-to-club contact at that point, a position which they have maintained.While talkSPORT later revealed that Guimaraes had agreed personal teams with Arsenal, Newcastle are maintaining their not for sale stance, as the north London club weigh up increasing their offer to £60m.The Daily Telegraph have since reported that the Gunners were set to pull out of the deal for the Brazilian, who felt they had been misled on the player’s price.Arsenal are said to have become interested in Guimaraes after they were told, via intermediaries, that he could be bought for £50m.This is reportedly based on a conversation between the club and Newcastle’s former co-owner Amanda Staveley, who said they would listen to offers of that size if the club failed to qualify for the Champions League, rumours which were later denied.Rumours debunkedWith conflicting reports emerging over Arsenal and Newcastle’s stances on Guimaraes, talkSPORT’s chief football correspondent Alex Crook has shared an update on the saga. Crook told talkSPORT: “I’ve mentioned Newcastle already in their ultimately fruitless pursuit of Johan Manzambi – another big blow for Eddie Howe in what’s already turning out to be a troublesome summer. “Anthony Gordon has left for Barcelona. Sandro Tonali has joined Tottenham for £100million and Bruno Guimaraes is also pushing to leave St. James’ Park.Mikel Arteta is looking to take his Premier League-winning side to the next level with the addition of GuimaraesGettyNewcastle have already lost a key midfielder with Sandro Tonali moving to TottenhamTottenham Hotspur FC“Conflicting reports this morning – some are suggesting that Arsenal are not going to pursue a deal. “They were told there was a gentleman’s agreement that Guimaraes could leave the club this summer – that’s been shot down by senior sources at Newcastle.”Arsenal to pay up?Explaining where this leaves both clubs, Crook revealed that Newcastle were now likely to demand in the region of £100m from Arsenal, having seen past and present midfielders depart for similar amounts.Sandro Tonali recently departed to join Tottenham in a £100m club-record deal, while ex-Magpies midfielder Elliot Anderson has joined Manchester City for £116m – the highest-ever fee for a British player.Newcastle consider Guimaraes as not for sale. He has two years left on his contract, and remain hopeful he will extend his stay.Crook continued: “I think Arsenal’s valuation of Guimaraes is much lower than what Newcastle are prepared to do business at. Guimaraes helped end a 70-year wait for a major trophy at Newcastle with League Cup glory last yearGetty“There is still a chance that they can persuade Guimaraes to stay and sign a new contract. “Certainly Newcastle’s stance all the way through this pursuit, this saga if you like, has been they don’t want to cash in on their captain. He’s one of the players they do want to keep at St. James’ Park. “In fact, as I’m recording this from New York, I’ve just been sent a message by somebody very high up at Newcastle suggesting their asking price for Bruno Guimaraes would be nearer the £100m mark. “That’s what they sold to Tonali for. Elliot Anderson went for at least £116million with add-ons. “They’ve looked at those deals, Newcastle, and they are determined to drive a hard bargain for Guimaraes.”Guimaraes has played a total of 195 matches for Newcastle since joining the club in 2022, and has since helped them to Carabao Cup glory in 2025, and Champions League qualification twiceGuimaraes’ 2025/26 season proved to be his most fruitful in the Premier League to dateDespite a disappointing 2025/26 season for the club, which saw them finish in 12th spot, the Brazilian proved to be a bright spark.He chipped in with nine Premier League goals – his highest tally in a single campaign in England to date.And he also provided seven assists in 41 games across all competitions for the Toon outfit.
