GABRIEL put Arsenal back on top of the Premier League with the winner in their high noon showdown.
A clumsy error by Chelsea’s normally super-cool defender Thiago Silva allowed the defender just enough time and space to prod the ball over the line from a corner in the 63rd minute of a tight London derby.
Veteran centre-half Silva completely missed his attempt at a clearance from a corner by Bukayo Saka on the edge of the six-yard box.
The embarrassing air-kick meant the ball fell to fellow Brazilian Gabriel who was able to stab the ball home from less than a yard out.
Arsenal were in control from start to finish even though it took a howler from the opposition to gift them the breakthrough in a tense lunchtime match.
