Arsenal are preparing to make an opening bid for Bruno Guimaraes, although the club accepts its initial offer is unlikely to persuade Newcastle United to part ways with the Brazilian midfielder.

The Gunners are expected to submit a proposal worth around £70 million, but Flashscore understands they are prepared to return with an improved offer should their first approach be rejected.

Sources indicate that Guimaraes is open to the move to the Emirates Stadium, with personal terms already understood to be in place. Arsenal are determined to avoid missing out on another of their priority transfer targets this summer.

The north London club recently suffered a setback in the market after Morgan Rogers completed a £117 million move from Aston Villa to Chelsea. Arsenal had valued the England international at around £80 million, only for Chelsea to secure the deal with a significantly higher bid.

That experience has reinforced Arsenal’s willingness to act decisively in their pursuit of Guimaraes.

While the club is prepared to increase its offer, sources suggest Arsenal are reluctant to go beyond a package worth just over £80 million, including performance-related add-ons. That figure is viewed internally as the maximum they are willing to pay.

Newcastle, however, are expected to demand a considerably higher fee, with a valuation closer to £100 million.

The Magpies are believed to view Sandro Tonali’s reported £100 million move to Tottenham Hotspur as a key benchmark in any negotiations involving Guimaraes.

Despite Arsenal’s growing interest, Newcastle’s stance has not changed. As of Thursday evening, club officials remained adamant that they have no intention of selling the Brazil international during the current summer transfer window.

A formal bid from Arsenal is expected to arrive in the coming days, with the Premier League runners-up hopeful negotiations can gather pace before the window closes.
