SOUTHAMPTON'S Polish international goalkeeper Artur Boruc played a major part in helping Arsenal move four points clear at the top of the Premier League during the clash between the sides in London.
Fourth-place Southampton, beaten only once previously this season, were holding their own until Boruc tried to dummy his way past Arsenal striker Olivier Giroud in the 22nd minute and was dispossessed by the Frenchman, who scored.
Giroud sealed the win from the penalty spot in the 86th minute.
The result means Arsenal has now won five consecutive home games in the league.
