It is that time of year again where giant-killings and magical moments happen.

We have seen it time and again over the years in the FA Cup that nothing is to be taken for granted.

Some of those giant-killings that are still talked about include games such as Hereford United beating Newcastle 45 years ago.

Wycombe Wanderers have also produced slayings of their own, especially when beating Leicester 2-1 in 2001 thanks to Roy Essandoh’s late winner.

Now, the tables are turned, much like last season when Stourbridge came to town in the third round.

Stourbridge came mightily close to getting a replay but Adebayo Akinfenwa broke their hearts with a thumping header to win it late on.

This time, Leatherhead are the opposition at Adams Park, the lowest ranked side left in the FA Cup this season.

This is the furthest they have gone since 1975 when they also reached the second round and Blues boss Gareth Ainsworth is definitely under no illusion as to how difficult this game will be.

He said: “For me, this is the toughest game of the season.

“Not just that the opposition will provide a threat but because of everything that comes with it.

“This competition only comes along once a season and you want to try and grasp hold of it for as long as you possibly can.

“I was lucky enough to be a pundit for the Billericay replay and they played some great football to beat them off.

“I would say Billericay have a similar wage bill to ours so for Leatherhead to beat them was fantastic.

“It should be a great occasion, similar to the Stourbridge game last year. I just want the boys to do a professional job, like they did against Solihull Moors and I am looking forward to it.

“You cannot take these non-league sides lightly and there are some good players out there and good talents.

“It can be difficult to get footage of these non-league sides but our preparation will be good.

“We will be aiming to get in that third round. Believe me, for a club like ours to be in the same pot as the likes of Manchester United is fantastic and we are going for the win but it will be a potential banana skin and hopefully there will be no upset and we can get the win.”

Although the importance of the FA Cup has worn off for the bigger clubs in recent seasons, Ainsworth still loves the competition he has grown up with.

He added: “It is a competition that I would never take lightly.

“From the age of about eight or nine years old, cup final day was shut down in our house. The whole family would watch the build-up and see how the teams got to the final and then watch the game.

“I am very proud that I am in the oldest cup competition in the world and what is a fantastic cup competition for our country.

“We don’t want it diluting and we don’t want the FA Cup being anything other than the special trophy that it is so I will be playing my best side and hoping to get into round three.”
