I don't know, but I understand as a fan that if a billion was pumped into the squad and I pay horrendously ticket prices that there is some demand created for success on the fans' part.
Chelsea really spent a lot of money last season. In Todd Boehly's era Chelsea had spent around a billion pounds on player purchases and unfortunately they failed in any competition. I think it is natural that fans are disappointed with the previous manager because the money given was wasted because they failed to choose good players. This is different from Roman Abramovich's era who also bought a lot of players but they managed to become a successful team.
What should they expect in your opinion? You are right about Lampard though, he hasn't been doing very well.
I don't know which fan asked to send a message to Lampard. I know Lampard is a Chelsea legend and was one of the best midfielders in the world at that time. But his career as a coach was not so good. Did the person who asked to send a message think that Lampard would be like Alonso because they were both midfielders?
