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."
