Newcastle's Rebuild: Guimarães Nears Exit, Martinelli Talks with Arsenal

Newcastle United are being ripped from their recent past, piece by piece.

Sandro Tonali. Anthony Gordon. Eddie Howe. Now, the captain.

Bruno Guimarães, the heartbeat of the side that dragged Newcastle back into the Champions League and finally delivered domestic silverware with a League Cup triumph, is close to leaving. Arsenal have agreed a deal in principle for the Brazilian midfielder, believed to be around €90 million, and with that, the last defining pillar of the Howe era looks ready to fall.

If and when that move is completed, Newcastle will not just look different. They will feel unrecognisable.

A squad rebuilt, but not yet improved

New faces have already arrived. Bazoumana Toure, Sean Steur, Ewen Jaouen and Aladji Bamba have been brought in as part of a sweeping rebuild. A move for goalkeeper Lukas Hornicek is also thought to be close.

On paper, it’s a flurry of activity. In reality, it does not yet add up to a better team.

Newcastle finished 12th in the Premier League last season. Mid-table. Flat. A long way from the intensity and cohesion that once made St James’ Park one of the most intimidating grounds in the country. Losing Guimarães on top of Howe, Tonali and Gordon only deepens the sense that the club is stepping into something unknown rather than calmly evolving.

They need more. More certainty. More proven quality. More players ready to carry a team, not just grow with it.

Which is why the gaze has turned, intriguingly, back towards Arsenal.

Martinelli on the market – and on Newcastle’s radar

Arsenal, newly crowned Premier League champions, are not immune to change either. Their squad, deep and ruthless, is now at the stage where familiar faces can be moved on to make room for the next wave.

One of those could be Gabriel Martinelli.

According to reports confirmed by Caught Offside (via Football FanCast), Martinelli could leave the Emirates this summer, with Newcastle United among the clubs to have registered concrete interest. Manchester United and Bayern Munich are also in the frame.

Arsenal are thought to want around £50 million for the Brazilian. Talks are underway, though there is no indication yet that negotiations are at an advanced stage. What does seem clear is that Martinelli is open to a move, keen to restart a career that has stalled in north London.

That price tag is significant. At this point, it is difficult to see a long queue of clubs willing to pay £50 million for a player who has slipped down the pecking order at the champions. Yet that is exactly the sort of market where Newcastle, if they judge the opportunity correctly, can strike.

Is Martinelli the right fit for Newcastle’s reset?

There was a time when Martinelli looked like one of Arsenal’s brightest prospects, a livewire forward who played every minute as if it might be his last. Those days feel distant now.

His influence has faded. His role has shrunk. At Arsenal, he has gone from cornerstone to option.

For the player, a move makes sense. For Newcastle, it could be more than that – it could be a statement that this rebuild is not just about potential, but about players who have already proven they can live at the top of the Premier League.

Martinelli would walk into a prominent role on Tyneside. He would bring experience of a title-winning dressing room, Champions League football, and the pressure of competing at the sharp end of the table. He would also bring goals, direct running and an edge in transition that Newcastle sorely lacked last season.

This is exactly the kind of environment that might allow him to thrive again: a club desperate for a new attacking leader, a fanbase that embraces hard-running, aggressive forwards, and a manager needing a focal point for a new project.

The risk is obvious. The reward, if he rediscovers his best form, is just as clear.

The 45-day rule and the likely shape of a deal

There is another layer to any potential move: the 45-day transfer rule. Under those constraints, a straight permanent transfer to Newcastle is complicated.

Any deal would most likely be structured as a loan with an option or obligation to buy, allowing Newcastle to stay within the rules while still effectively committing to Martinelli as part of their long-term rebuild.

That kind of arrangement suits all sides if the numbers align. Arsenal get a clear path to a sale at close to their valuation, Newcastle get flexibility and protection, and Martinelli gets the platform he needs without the move being bogged down by regulatory hurdles.

The question now is simple: as Bruno Guimarães prepares to swap black and white for red and white, will Newcastle push hard enough to bring one of Arsenal’s lost stars the other way?

Because if this is to be a new era on Tyneside, it cannot just be about who leaves. It has to be about who is trusted to lead what comes next.
