If we hadn't sold Hakimi Chelsea would have never offered so much for Lukaku. Instead they would try to lowball us knowing we need to find 60-70m. Same thing Man Utd did with Perisic when we needed to find 40m in 2017.
or we could just not announce the world that we're screwed if we don't come up with the funds.
Perisic offer was actually 45m, we were asking for 55m. It wasn't during the FFP madness, it was an ongoing issue from mid July to early August. They didn't want to give that big of a sum for a player nearing his 30s without much PL marketability. Only reason they chased him was Mourinho requesting him.
We wanted 70m in 2018 after the World Cup, they came up with 60m or 65m by including Darmian (rated 20m lol) that time. After scoring against England in the semi and also scoring in the final, the Utd management felt his name was worth the premium, but they wouldn't do 70.
They ended up with no one else for that position in 2017, typical, same thing they did when they failed to get Skriniar, Alderweireld and Maguire in 2018. Eventually they signed Sanchez in the 2018 winter, which doesn't really qualify as a Perisic alternative.
