FORMER Worcester City midfielder Sam Wedgbury has warned another of his former clubs Sheffield United against taking the FA Cup minnows lightly.

After knocking out Solihull Moors and higher-ranked Gateshead this season as well as their famous 2-1 win at Coventry City in the 2014-15 first round, the Aggborough tenants are no strangers to cup upsets.

Wedgbury joined the Blades from Worcester in 2006 as a promising teenager but failed to make a first-team appearance for the now-League One promotion-chasers.

Now 26, he is back in non-league football driving Forest Green Rovers' charge towards promotion from the Vanarama National League.

Oldbury-born Wedgbury believes it would be a big error for Nigel Adkins’ side to dismiss the threat posed by Carl Heeley and Matt Gardiner’s National League North side at Bramall Lane tomorrow (3pm).

He said: “They will be able to come with nothing to lose and everything to gain.

“It’s a win-win situation, to be honest, when you’re in City’s position ahead of a game like this.

“The Worcester lads are going to be giving absolutely everything to prove they can compete on a level like this.

"There will be people ready to head boots and put their bodies on the line.

"So, despite the respective positions of the two clubs, this could turn out to be the toughest test United have had yet (this season).

“City’s experienced players, like Deon Burton, will want to show they’ve still got it and the younger ones will want to show they are capable of competing on this stage. The reasons are different but the motivation is the same.”

Wedgbury, who still has a home in Sheffield, added: “Without a shadow of a doubt, the underdogs in these situations raise their game by about 10 to 15 per cent. Possibly even 20.

"I know because I’ve been there. Back when I was at Macclesfield Town, we showed that against Cardiff City and then, even though we lost, we gave Wigan Athletic a massive scare.”

Wedgbury netted on his City first-team debut aged just 16 in a 7-0 FA Cup success over Bemerton Heath Harlequins in 2005 and was the club's youngest goalscorer.

Of his time at Sheffield, he added: “It was amazing for me. Working alongside people like Gary Speed and Chris Morgan taught me so much.

"How can you not learn from top professionals like that? Back then, it was really difficult to break into the first team at United.

“We’d come down from the Premier League but were always challenging at the top of the Championship."
