Last season, Lincoln boss  Danny Cowley was a PE teacher and the part-time manager of Braintree Town. 

Soon he'll be shaking hands with Arsene Wenger, his team 90 minutes away from a Wembley appearance and the FA Cup semi-finals. Stranger things have happened you know... 

Drink it in Imps fans.

Arsenal  make two changes to the side that lost 5-1 at home to Bayern Munich in the Champions League on Tuesday. 

Petr Cech returns to replace David Ospina in goal, and Kieran Gibbs comes in for Nacho Monreal at left-back. 

Arsenal XI:  Cech, Bellerin, Mustafi, Koscielny, Gibbs, Xhaka, Oxlade-Chamberlain, Ramsey, Walcott, Sanchez, Giroud.

Lincoln  make four changes to the side that beat Braintree Town 4-0 in the National League on Tuesday. 

Nathan Arnold, Matt Rhead, Alan Power and Jack Muldoon all come in, with Elliott Whitehouse, Josh Ginnelly, Jonny Margetts and Lee Angol dropping out. 

Lincoln XI:  Farman, Wood, Habergham, Waterfall, Muldoon, Power, Rhead, Hawkridge, Raggett, Arnold, Woodyard.

Afternoon everyone. 

Lincoln, the National League leaders, have already achieved the unthinkable in getting here.

This is the first time a non-league side has reached the FA Cup quarter-finals in 103 years.

The Imps were down to play at home to Chester today. How about the Emirates instead? 

Forget the ongoing 'Wexit' sagas for a moment. Today's all about whether this group of players can achieve what would surely be the greatest FA Cup shock of all time.

"It's like a priest," said Arsene Wenger. 

"You're a football priest. Are you ready to sacrifice your life?"

Arsenal manager since October 1996, Wenger has never had to endure a period quite like this.

The fan protests calling for him to go. The 10-2 aggregate mauling by Bayern Munich. Yet another season falling short. His future is in his hands - what else, at a club so radically transformed by one man?

But will he stay beyond the end of the season? Or will he go - with a growing number of fans calling for just that to happen. Would victory today help convince the doubters? 

Not much. 

Defeat? Well that would be seismic.
