Arsenal have reportedly shocked Liverpool by agreeing a four-year deal with Juventus midfielder Arturo Vidal.

According to Calcio Mercato Web, the Gunners have spoken to the Chilean's agent Fernando Felicevich and come to an agreement with him during a recent visit to London.

Vidal has been a target for Premier League clubs since last summer, with Manchester United close to landing him in the summer, but a deal failed to materialise due to Louis van Gaal's concern regarding the Chilean's knee injury that he sustained ahead of last summer's World Cup.

Arsenal were also linked with the Chilean last summer, but it was Liverpool who were leading the chase this time around as they look for a replacement for the departing Steven Gerrard.

The north London club seems to have stolen a march on their rivals, to land the highly coveted midfielder. Arsenal already have Vidal's compatriot and friend Alexis Sanchez at the Emirates Stadium and the two also share the same agent making it easier for the Gunners to approach the player regarding a move.

The report claims that Arsene Wenger is looking for a box-to-box midfielder, who can chip in with goals and has identified the former Bayer Leverkusen star as the perfect player to complement the likes of Francis Coquelin, Aaron Ramsey and Santi Cazorla in the middle of the park.

It is reported that Juventus will allow Vidal to leave, as they are looking to boost their coffers to strengthen their squad in the summer.

It is believed that they will hold on to Paul Pogba for another season with Barcelona planning a move for the Frenchman in 2016 due to their transfer ban, which forbids them from signing any player this summer.

This will come as a big blow to Brendan Rodgers, who was said to be keen on signing the Chilean, who has been impressive for the Serie A champions this season, as they won their fourth consecutive Scudetto.
