Arsenal's medical team will stay in constant contact with their Chilean counterparts in an ongoing effort to keep Alexis Sanchez from making a concerning groin injury worse, reports MailOnline.
The forward has been a standout performer in Arsenal's last two Premier League games, first scoring a hat-trick against Leicester City, followed by a brace against Manchester United.
Arsene Wenger later confirmed that Sanchez had sustained the injury in the 3-0 win over Louis van Gaal's men, and seemed worried by the fact that he had flown to South America to link up with Chile.

The Copa America champions face a tough game against Brazil on Friday followed by a game against Peru next week. Wenger admitted that Sanchez wanted to play in both games, but Arsenal's medical staff are concerned that doing so could cause a real issue.
Sanchez was assessed at London Colney and physios are confident that it is not serious. Regardless, they are keen to keep in close contact with the Chile set-up to make sure no unnecessary risks are taken.
Hitting top form
Sanchez had failed to score for Arsenal before the 5-2 win over Leicester but followed up his hat-trick with a goal against Olympiakos and two against United. It seemed to suggest that Sanchez has finally rekindled his best form.
The 26-year-old is forming an exciting partnership with Theo Walcott and Mesut Ozil and is seen as key to Arsenal's chances of challenging for the Premier League title. A serious injury, sustained on international duty, is the last thing the Gunners need.
However, Sanchez's sheer hunger to play football leaves Wenger with little choice but to hope for the best.
