Three reasons why Preston will knock Arsenal out of the FA Cup

The 4-1-4-1 formation

Preston manager Grayson has operated several systems this season, meaning he has more than one option to choose from before facing Wenger’s team.

One of these is a 4-1-4-1 formation, a system that the Lilywhites have used three times in the Championship this season.

In this set up, they have won all three of their fixtures against Norwich City, Aston Villa and Bristol City; scoring five times and only conceding once in this set-up.

Will Grayson use the successful formation to tackle a weakened Arsenal side?
