Arsenal's Vieira appears to be injured already as he's pictured wearing boot

ARSENAL new boy Fabio Vieira has picked up an injury BEFORE the club's pre-season tour.

Vieira, 22, joined the North London side last month in a deal worth £34million.

Upon his arrival, Arsenal boss Mikel Arteta hailed him as a "special" player that is set to bolster his team's attack.

He said: "I am very excited that we have identified and signed such a special talent.

"Fabio is a very creative player that will bring high quality and versatility to our attacking play."

However, the midfielder has already hit a stumbling block before even putting on the red shirt.

A picture posted on Instagram clearly shows his left ankle in a protective boot, indicating that he has already sustained an injury.

But according to football journalist James Benge, it is just a minor foot issue.

Vieira now faces a race against time to prepare for the Gunners' upcoming pre-season tour in the United States.

All of Arsenal's new signings are expected to make their club debut's before the season starts next month.

Arteta has already confirmed that 19-year-old Marquinhos will be given his chance to shine following his £3m transfer from Sao Paulo.

Matt Turner is also set to appear between the sticks upon his return to America.

And new No.9 Gabriel Jesus is expected to alternate with Eddie Nketiah in attack.
