Which signing would make Hazard "the happiest man in the world"?

In addition to today being Champions League final day, it's also everyone interview Eden Hazard day. The reigning Premier League player of the season will be captaining his country for the first time tomorrow, and that means everyone wants a piece of the 24-year-old.

What are his goals for next year? The Champions League final, he hopes. How about captaining Chelsea? Not an objective, but he'd like to. And on it goes. Naturally, he was also asked about transfers, and the prospect of Red Devils teammate Christian Benteke joining the Blues:

If Christian signs with us, I would be the happiest man in the world. I have a great relationship with him and would like nothing better than to play with him. Christian is 25. He is at an age where he has to make a good career choice. Not that Aston Villa is a small club but he has already played many great games and can now play in the Champions League.

Although I like Hazard being happy, I still can't see this actually happening. Benteke would be a great replacement for Didier Drogba in a vacuum, but the fight we'd have to put up to pry him away from Aston Villa (and I liked how diplomatic Hazard was about their current status) would probably consume far too much of the club's resources. That said, I couldn't really see Radamel Falcao happening and people are still talking about it anyway.
