To win the Premier League title you have to go through the pain barrier and Gabriel Martinelli did just that to deliver another vital win on the road for Arsenal.
A split second after releasing the shot the found the corner of Danny Ward’s net in the first minute of the second half, Martinelli took a fearful whack to the knee from Wilfred Ndidi, who had tried in vain the block the shot.
The Brazilian was briefly in agony but fought on to typify a victory that once more underlined the Gunners’ credentials as they moved five points clear at the top, with Manchester City playing at Bournemouth later on Saturday.
