Manchester City set up a FA Cup semi-final date with Arsenal after defeating Newcastle United 2-0 in their quarter-final clash on Sunday evening.

Steve Bruce's charges eventually conceded a penalty ten minutes before the break after Federico Fernandez pushed Jesus blatantly inside the box. Kevin De Bruyne was assigned to the penalty spot and made no mistake from 12 yards out.
Newcastle had new found energy in the opening exchanges of the second stanza and they were gifted a chance to equalise in the 68th minute after a sloppy play at the back by City saw Dwight Gayle have a clear sight on goal from Allan Saint-Maximin's square pass but the English striker placed his shot over the bar.
The hosts paid the price for that miss as immediately thereafter, as Raheem Sterling made it 2-0 for City with a well placed strike away from Darlow after cutting inside on the right flank from second-half substitute Phil Foden's pass.
The Magpies were deflated after conceding the second goal, with the Citizens fashioning chance after chance but only to be thwarted by Darlow's heroics.
