Kai Havertz has added fuel to the fire that he's set to join Chelsea by liking a post on social media.Speculation has been building over the future of the 20-year-old who is said to be attracting the interest of clubs such as Manchester United, Bayern Munich, Barcelona and Real Madrid.The Daily Mail reported that the Blues are looking to tie up a move for the Bayer Leverkusen skipper as they look to take a proactive approach in the summer market.It's claimed that a move could cost in the region of £75million - a significant outlay considering the early business that Chelsea have already completed.While it's too early to say whether the Blues will solidify their early interest with a bid, the German midfielder has certainly stoked the fire.After a Chelsea supporter replied to a post on the club's Twitter account by saying 'announce Havertz', the fan got the surprise of a lifetime when it was liked by the man himself.

The 'like' has now been removed.

Whether this means anything for Chelsea's pursuit remains to be seen, and it's likely that this light-hearted interpretation is nothing more than a bit of fun.

Whatever the reason, it certainly is enough to get supporters excited.

GIVEMESPORT'S Phil Spencer says...

The transfer window isn't even open and we're already gripped by what is going on.

Chelsea have been quickest out of the blocks with two huge signings all-but wrapped up, and it seems that they aren't finished yet.

In fact, they're only just getting started.

If they can tie up a deal for Kai Havertz that would one heck of a coup - especially if they are beating some of Europe's biggest clubs to the punch.
