This one was never likely to be straightforward.
That matters. A new manager taking charge is hardly the moment a club wants to lose one of its central personalities. If Arsenal are serious, they may need to test Newcastle’s resolve again - and probably with a bigger offer.
The comparison with Debuchy is not exact, but it is revealing. In 2014, Arsenal moved for a player who had impressed on the international stage and who saw the switch as a step up. Debuchy also spoke warmly about his old club, calling Newcastle supporters “passionate people”.
That is the tension here. Arsenal can offer prestige, title contention and the attraction of joining an established contender. But Newcastle are no longer simply a selling club waiting to cash in at the first big approach.
This pursuit says plenty about Arsenal’s priorities.
For now, the first answer from Newcastle is a firm no. The next question is whether Arsenal return with improved terms - and whether Guimaraes becomes the defining transfer storyline of the final stretch of the window.
