Walcott: Alexis signing give Arsenal back the fear factor

The Chile international joined from Barcelona in a £31.8 million deal and his new team-mate believes it is the type of signing that should scare their Premier League rivals
Theo Walcott has hailed Arsenal for signing "world-class" Alexis Sanchez and fired a warning to the rest of the Premier League ahead of the new season.

Alexis signed from Barcelona for £31.8 million - becoming the north Londoners second most expensive signing of all-time, following the £42m acquisition of Mesut Ozil last summer - and says he is targeting the Premier League title in his first year.

And Walcott, who is still recoving from a serious knee injury, has stated how important he feels the signing will be as Arsenal look to add to the FA Cup they won in 2013-14.

He told the club's official website: “Sanchez is a world-class player and I enjoyed watching him play for Barcelona and for Chile at the World Cup.

“He’s still very young as well and he is going to show so much pace and power, which we lacked a bit last year. With me and him on the flanks, a lot of teams won’t be looking forward to playing Arsenal this year!

“There’s a great buzz around the club at the moment. He is a marquee signing and something that the club has pushed on to: first you had Mesut Ozil and now it is Alexis Sanchez. Who knows where it is going to stop?

“It is great to learn from these players, and I cannot wait to play alongside him. I am really looking forward to it.”

The Gunners' pre-season gets underway on Saturday where they face Boreham Wood at Meadow Park, before a trip to America for a fixture against New York Red Bulls on July 26.
