A fine goal from Brazilian forward Gabriel Martinelli earned Arsenal a narrow 1-0 win at Leicester City on Saturday, giving the Premier League leaders a five-point lead at the top of the standings.

January signing Leandro Trossard arrowed a stunning strike into the net midway through the first half, but the Belgian was denied his second goal for Arsenal after VAR ruled Ben White to have fouled Leicester goalkeeper Danny Ward in the build up.

It took the dominant visitors until the first minute of the second half to break the deadlock, as Martinelli raced onto a Trossard pass and stroked home what proved to be the winner.

The hosts did not look like getting back into the contest, with Arsenal seeing out the win that stretches out their lead over Manchester City, who play Bournemouth later on Saturday. Leicester stay 14th, three points clear of the relegation zone.
