I've got 2 in mind which were equally great but will go for Joe Morrell for his assist for our third goal against Ipswich in the home win in December.
Picked the ball up about 40 yards out and just ran at and through their defence with close control Messi would have been proud of. Gets to the bye line and pulls it across for a virtual tap in for Tyler Walker
I nominate Grant's assist for Hopper to score Vs Burton. Not spectacular, but unselfish when he must have been tempted to try himself, and resulted in a valuable goal.
