Declan Rice is still monitored by a few big Premier League teams these days. Arsenal, Chelsea and Manchester United have him on their radars.
Well, it is somewhat certain that Declan Rice is going to leave West Ham next summer, but i don't think Chelsea are going to sign him, even if they want to/should (because Kante is prolly leaving), i think Chelsea aren't going to sign him because of the amount of money they have spent on players in this January winter transfer window, they surely can't go on another spending spree in the summer, that would definitely get them into FFP trouble, and as we know it Declan Rise could cost nearly 100 million pounds, so that is quite a lot of money.
Having said that, between Arsenal and Manchester United, i think the Englishman might favor Arsenal, they are more of a stable club than Manchester United right now, and if Arsenal go on and win the EPL it becomes a whole lot easier for them to allure Rise and players of similar and better quality.
