Arturo Vidal´s agent Fernando Felicevich has flown into London, increasing speculation that the Juventus midfielder is on the brink of a move to Manchester United.

The Chilean agent was spotted at Wembley during Arsenal's 3-0 victory over Manchester City in the Community Shield on Sunday.

Felicevich was said to be in London to support Alexis Sanchez, as he also represents the new Gunners star, but according to La Gazzetta dello Sport he may have taken advantage of his visit to England to finalise Vidal's move to Old Trafford.

Nevertheless, the Italian newspaper claims the negotiations between the clubs face a crucial week as United would like to close the deal before the beginning of the Premier League season on Saturday.

Vidal himself has also added fuel to the rumors after he was pictured signing a United shirt during Juventus's pre-season friendly game against an A-League All Stars side in Sydney.

The 27-year-old is indeed believed to have already agreed personal terms on a five-year-deal worth around £180.000 per-week – with United now trying to iron out the deal with the Serie A Giants.

La Gazzetta dello Sport claims Louis Van Gaal´s side recently launched a £47.5m bid to secure the services of the midfielder, and are prepared to facilitate the negotiations by including Chicharito Hernandez as part of the deal.

Following the arrivals of both Ander Herrera and Luke Shaw earlier in the summer, Van Gaal is reportedly planning to complete the overhaul of his squad before the end of the transfer window with Vidal his top priority.

Nevertheless, the new United boss is also keen on adding at least one centre-back, with Mehdi Benatia among those linked, as well a versatile winger, with both Angel Di Maria and Juan Cuadrado mentioned in dispatches.
