The discussions have already started, might as well have a dedicated thread.

So let's see who is up for grabs this window. As I have not caught up with all the rumours, I just looked up at some odds.

Alexis Sanchez: Rumoured at quite a bunch of clubs. No one really knows where he might end up, especially if Arsenal miss the Top 4 trophy. Top bookie favourites are Chelsea, City and PSG, but any top club might just throw their hat into the ring.

Antoine Griezmann: For him it seems to be either stay or United. But if United also fails to qualify for the CL, they will have to dig deep into their TBTVDITW money.

Daniel Sturridge: Has been linked to a bunch of English clubs and PSG. Not sure if a move makes sense for him under Klopp.

Eden Hazard: Can't really see him moving away from Chelsea, but Real seems to me the most likely club after that. Would probably be a close-to-world-record transfer sum if it happens (contract runs out in 2020).

Mesut Özil: Similar to Sanchez, he might jump ship if Arsenal miss the UCL, and his next club could be anywhere from Manchester to Madrid. And Juventus, and Bayern. Still has a year on his contract as well, just like Alexis. WENGER OUT!

Romelu Lukaku: Let's face it: Everton will probably not be good enough to reach the CL in the near future, so Lukaku has been rumoured to leave multiple times, the most likely targets Chelsea and United. Contract until 2019.

Sergio Aguero: Selling Aguero might make 8bus' pants explode, but it seems unlikely at this point. City would lose their most succesful striker, and good replacements are rare these days. Can get 5/1 on Madrid tho, so idk.

Wayne Rooney: Already earns a ****ton of money at United. But he might be tempted to earn two ****tons of money in China or the MLS.

Obviously this was very EPL-centric. But other leagues might have their transfers discussed here as well:

Which Dortmund player will join Bayern this year?
Has Real bought a new fax machine and will have another go at De Gea?
Will PSG spent another quarter billion to finally qualify for a CL semifinal?

If both Arsenal and United miss the Top 4, things might get... very busy™ in this transfer window.
