Arsenal manager Mikel Arteta was surprised by the lack of consistency in the refereeing during Arsenal's 1-1 draw with Brighton and Hove Albion on Saturday. Declan Rice was sent off just after the break after the winger appeared to kick a loose ball after the referee's whistle. Arteta says the referee has the right to make that decision but questioned why he let other similar incidents slide, including one in which João Pedro kicked the ball wide in the first half but was not penalised.
