A move for Seys would be easy to understand from both Manchester United and Arsenal.
For United, the left-back position has looked like an area that needs durability and succession planning as much as immediate quality. For Arsenal, the attraction appears to be depth, versatility and long-term development rather than a short-term headline signing. A young defender from Club Brugge also fits the kind of modern recruitment model elite clubs increasingly prefer: high ceiling, room to grow, and resale protection if the move does not fully click.
The same update says Arsenal are unlikely to consider selling Martinelli, and that Atletico Madrid are holding firm on Alvarez. Those two lines matter.
Selling clubs know that proven attacking players are the hardest pieces to replace. Even when form fluctuates, pace, directness and end product remain premium assets. That is why interest alone rarely changes a club’s stance. Unless a huge offer arrives, teams with top-level ambitions usually keep the forwards they trust.
Elsewhere, Besiktas reportedly remain interested in Willock, while West Ham have made a bid for Parrott. These may not dominate the window, but they can still be significant.
Willock would bring athleticism and forward running to a midfield. Parrott looks like the type of striker move clubs make when they want mobility, hunger and potential growth rather than a blockbuster fee.
The next few days will show whether interest in Seys becomes a serious battle, and whether the firm stances on Martinelli and Alvarez soften. As ever in August, one deal can quickly change the mood of an entire window.
