Alexis Sanchez keeps holder Arsenal on course for FA Cup history

Arsenal's bid to become the first team to win the FA Cup three times in succession since 1886 remains on course after Alexis Sanchez sealed Saturday's 2-1 win over Burnley in the fourth round.

The holder had a first-half scare when Burnley's Sam Vokes cancelled out Calum Chambers' 20th-minute opener, but Sanchez's second-half goal ensured the Premier League side avoided an upset against Championship opposition.
