Chelsea buys zaha sky news
I think there may be some confusion here!
To clarify, there has been no official announcement from Chelsea FC or Crystal Palace FC that suggests Wilfried Zaha has been sold to Chelsea.
In fact, Wilfried Zaha has been a key player for Crystal Palace FC since his return to the club in 2013, and has consistently been one of the team's top performers. He has also been a regular member of the Ivory Coast national team.
Sky News is a reputable news organization, but I'm not aware of any credible reports or sources that suggest Zaha has been sold to Chelsea. If such a deal were to happen, it would likely be widely reported by multiple sources, including the clubs themselves, the media, and transfer news outlets.
So, to summarize, there is no evidence to suggest that Wilfried Zaha has been sold to Chelsea FC, and any reports to the contrary are likely to be speculative or inaccurate.
