It seems like you're referring to a news article or a rumor about a potential transfer deal involving Manchester United and a player worth £100m.

To clarify, could you please provide more context or information about the article or rumor you're referring to? Who is the player, and what is the nature of the transfer rumor? Is it a done deal, or is it still in the negotiation stage?

Additionally, it would be helpful to know what "opens door to summer move" means in this context. Is it suggesting that the player's current owner is willing to sell him, or is it indicating that there's a possibility of a transfer happening in the summer transfer window?
