Looking at who is reffing the other Cup games it could have been a LOT WORSE..
the totally erratic Mason (crazy at Arsenal - awarded us a goal that was miles offside, terrible in the home game against West Brom when Baines was nearly decapitated in the box which lead to Arteta getting a red card, awful at Blackburn with the 3 penalty awards - all dubious), Pawson (first season in the PL apart from one game) and the utterly terrible Anthony Taylor (who gets to give City a bye into the semis) - Taylor reffed the game at West Ham last season when he sent off Cole and Gibson, he also ignored the blatant foul on Baines at Cardiff and gave the powder puff one on Benteke at Villa. Also sent Billy off at West Brom.
