Jose Mourinho is looking to significantly strengthen his Chelsea squad during the summer transfer window, and it appears he plans on doing so by bringing a host of players from La Liga to Stamford Bridge.
Cesc Fabregas was the first to make the move from Spain to London, as shared by Sports Illustrated's Grant Walsh:
Several more are rumoured to be on their way to Chelsea, so let's have a look at which La Liga players might be suiting up for the Blues next season.
The fact the Brazilian-turned-Spaniard is on this list isn't a huge surprise—the fact he hasn't officially signed for the club is. This move has been rumoured for months now, and Costa was widely expected to sign his first deal with Chelsea well before the World Cup.
That didn't happen, however, and as reported by Sport (h/t to Sky Sports' Lucas Brown), it doesn't look like even Costa knows what the future will hold, although he did confirm he has Chelsea on his mind:
At the moment I am not paying attention to it because I am thinking about the World Cup, but it is clear that my future lies more with Chelsea than with Atletico Madrid.
Atletico has been my home, my life and I have great feelings towards the club, but things happen in life and one has to accept them.
I do not know what the situation is because I have not been involved in all that.
Chelsea want Costa to help solve their striker conundrum, with a consistent scoring threat perceived as the Blues' No. 1 need going into the summer transfer window. While there are some health concerns, Costa was one of the world's most productive strikers in 2013-14.
His lack of success during the 2014 World Cup can't be held against the forward, as Spain as a team struggled to put together a meaningful campaign. As of right now, this deal still looks very likely, though Chelsea will want to keep a close eye on how he performs in Spain's final World Cup match.
Atletico Madrid won La Liga last season, so it's no surprise Mourinho has his eyes set on several of their players. Left-back Luis has a £20 million release clause in his contract, and per Goal's Wayne Veysey, the Blues are willing to trigger it.
The Spanish champions were well aware Luis could be leaving the club during the summer and have already signed a replacement, per Veysey, so if the player is keen on making the move, there should be little standing in Chelsea's way.
Luis is an experienced, smart full-back who prides himself on his defensive prowess, and while he isn't a particularly flashy player, he's a very useful option to have as part of your back-line.
Cesar Azpilicueta is the Blues' designated starter at left-back, and while the Spanish international performed admirably last season, he just doesn't offer the same defensive quality as Luis does.
As if signing former Gunners skipper Fabregas wasn't bad enough, the Blues are now reportedly looking into adding Song as well, per The Express's Anthony Chapman.
The Cameroon international failed to break into Barcelona's starting XI on a consistent basis due to the presence of Sergio Busquets, and with Frank Lampard set to leave Chelsea during the summer, his versatility in midfield could be a strong asset.
Song wouldn't be expected to be an immediate starter for Chelsea, but as a versatile option off the bench and some added squad depth, a £10 million move would make sense.
Mourinho has always put a premium on athletic midfielders able to both do the dirty work in front of the defence and contribute further up the pitch, and Song fits that bill. With Barcelona going through a bit of a rebuild during the summer, this is a move that could benefit all parties involved.
