Nigeria international Alex Iwobi was introduced in the 88th minute as Arsenal extended their unbeaten run in the English Premier League to thirteen matches after hammering West Ham 5-1 at the Olympic Stadium on Saturday evening.

Alexis Sanchez made the headlines with a hat-trick for the Gunners and the Chile star capped what was a wonderful display by scoring a brilliant lob in the 88th minute.

England star Alex Oxlade-Chamberlain, who picked up the Man of the Match award, made it 4-1 with a spectacular effort a minute after substitute Andy Carroll had pulled a goal back for the Hammers seven minutes from regulation time.

On 24 minutes, Mesut Oezil had got the ball rolling, tapping the ball in off an assist by Alexis Sanchez.

Iwobi, who was an unused sub versus Manchester United and Bournemouth, made his seventeenth appearance of the season against West Ham.

In the provisional standings, Arsenal are second with 31 points, three less than pacesetters Chelsea, while Liverpool, who play on Sunday are third with 30 points.
