Arsenal fullback Hector Bellerin insists there's no doubts about the commitment of Alexis Sanchez.

The Chile striker, who pushed to join Manchester City over the summer, was jeered by a section of the home support when coming as a substitute in victory over Bournemouth.

"Alexis is 100% focused on Arsenal," he told IBTimes.

"He did not start against Bournemouth after returning from his international team, but he came and showed that he will be 100% for the next matches."
