Arsenal are doing something that they have never done and spending this amount of money on a player because they have seen that to win trophies, heavy investment in the team has to be made. Declan must be very important to Arteta's strategy next season maybe that is why he has made him a top priority. 90 million is okay for him, and West Ham needs to consider it. If they refuse this, Arsenal may be forced to seek another alternative. West Ham may turn down this deal if they think that they will be able to get more from other clubs that are interested in Declan Rice too.
Arsenal are still in the process of hitting their transfer high with the Declan Rice deal, a second bid has been said to be rejected by Westham United, a deal worth £90m but it is not over yet as a third bid is expected soon. Arsenal seem very serious and ambitious this time, they are ready to splash cash to boost their squad for the coming season. I think Declan Rice and Lavia remain their top priority.
