PHOTO: Theo Walcott with Alexis Sanchez - speed kills!

Two Arsenal superstars of the Premier League have posed for a photograph that has been uploaded to Twitter.

Credited with completing a 100 metres sprint in just 10.6 seconds, Theo Walcott is revered as one of the fastest athletes in football.

The Englishman can run at speeds as high as 32 km/hour or 36 km/hour, depending on the data study conducted, but his new team-mate Alexis Sanchez is not far behind him, clocking speeds of 31 km/hour.

It is this shared quality in the fleet-footed Arsenal attackers that gives top gun Walcott confidence that the pair of them together can become "a deadly force" in British football.

Sanchez recently swapped Barcelona for Arsenal in a £32 million deal earlier in the summer and has been training in North London, alongside Walcott, while a 20-man squad toured the East Coast of USA before a pre-season midweek trip to Bad Waltersdorf in Austria.

Walcott is currently concluding his rehabilitation from a complicated anterior cruciate ligament injury and has also been training in England, away from the rest of the squad.

The 25-year-old, who was responsible for a goal or an assist once every 85 minutes on average from the few games he played last season, is expected to return to first-team duty in the middle of September.

Sanchez, meanwhile, could make an appearance at the annual, four-team Emirates Cup friendly competition this weekend.
