Alan McInally reflects on Arsenal's 4-1 victory over Sunderland at the Stadium of Light
Arsenal scored three goals in eight second-half minutes to thrash rock-bottom Sunderland 4-1 and keep pace at the top of the Premier League table.
Alexis Sanchez put the Gunners ahead in the 19th minute but Sunderland responded in the second-half thanks to Jermain Defoe's penalty after Duncan Watmore was brought down by Petr Cech.
With the game in the balance, Arsene Wenger introduced Olivier Giroud and the France international scored with his first touch in the 71st minute before securing the points with a deft header five minutes later.
Sanchez completed the scoring in the 78th minute, his 50th Arsenal goal helping the Gunners keep pace at the summit with Manchester City, while piling more pressure on Sunderland boss David Moyes.
Defeat leaves the hosts with just two points after 10 games, their -13 goal difference meaning this is the worst start to a Premier League season.
