Barcelona beat Paris Saint-Germain and Manchester City to the signing of coveted Ajax midfielder Frenkie de Jong.

The 21-year-old will officially arrive at the Camp Nou in the summer after a an initial fee of €75m was agreed between the two clubs - that could rise as high as €86m with variables.

De Jong signed a five-year deal and will reportedly pocket around €200,000-a-week, making him one of Barca's highest-paid players.

The Blaugrana are also keen to bring in fellow Ajax starlet Matthijs de Ligt, who is said to be keen on a switch to Catalonia.

It's safe to say the La Liga leaders are determined to make a big statement in the transfer market, having already announced the loan signing of Kevin-Prince Boateng.

But the same cannot be said for their bitter rivals Real Madrid, who are set to remain inactive this January after a very quiet summer.

Thibaut Courtois was the only high-profile arrival, with Cristiano Ronaldo departing the club.

And it turns out Barca's signing of De Jong will impact their transfer plans for the summer, as they are set to end their interest in long-term target Christian Eriksen, per AS.

The Tottenham playmaker's current deal runs out in 2020 and he is said to be keen on a move to the Spanish capital.

But after seeing Barca's fee for De Jong, Real are concerned about pursuing Eriksen as they believe his price will be inflated.

It is not yet known whether Los Blancos will identify new midfield targets or simply place faith in the options available to them.

Dani Ceballos is beginning to have an impact in the first-team, while Isco, despite a lack of game time, appears to be nowhere close to leaving the club.

It could be an interesting summer ahead for Real, as it's obvious the club do need some stellar reinforcements to keep pace with Barca.
