One benefit of Chelsea's terrible Premier League season is that it made the weaknesses to our current squad obvious enough that the board can't possibly miss them. Unfortunately, there are so many holes in that squad that it's questionable whether or not the board will be able to patch them all.
According to The Sun, Chelsea are targeting Oscar de Marcos as one player to add to the mix, with the Spaniard being a Ramires replacement, of sorts. De Marcos is a high-energy, versatile midfielder who can play all over the pitch, though he's typically deployed on the right be Athletic Club.
Due to the fact that de Marcos currently plays for Bilbao, he could be a difficult target to pry away. The Basque side's recruitment policy makes them very reluctant to sell their better players, and more often than not, those moves require paying the player's full buyout clause.
It's certainly worth noting that The Sun is rarely all that accurate, though they seem to have a better record when reporting Chelsea rumors than they do with other clubs, likely thanks to a certain troll in their employment. That said, selling Ramires without replacing him was an obvious mistake, so I'm glad to see links to a potential replacement, as he was one of the few players in the squad that was truly versatile, and could make our approach a bit less predictable.
