United defender Murray Wallace says Sunday's encounter with Chelsea is of huge importance for the club.
The Scot hopes he and his fellow Iron team-mates can cause something of an upset at Stamford Bridge.He is also hopeful a good performance against Guus Hiddink's side can be a springboard to another charge up the league table - much like the one which Wallace enjoyed in his previous loan spell with the club.
"It's a great game, a huge game for the club as well. A great one for all of the fans, and hopefully we'll go down there and cause an upset," he told The Iron PlayerHD.
"I think also it's a great game to kick on with the league campaign, and we'll go down to Chelsea, give it our all and see where it takes us.
"Hopefully we'll build on the confidence and take it into the league.
"The run we went on during the last month I was here was brilliant and I don't see why we can't do something like that again, and climb the table."
Wallace believes the tie which awaits on Sunday is one every footballer has aspirations of playing in, and for him it's no different.
With the third round FA Cup clash falling on his birthday, he hopes the day will be an even more special one for him.
He said: "I think it's one everybody dreams of. The big teams; Manchester United, Chelsea, Arsenal, and it'll be a great game to go and play against some of the best players in the world.
"Sunday's my 23rd birthday as well, so it'll be even better.
"My Mum was asking me what did I want for my birthday, and I said I'll take a goal at Stamford Bridge. So it means a lot to me to play against Chelsea."
After putting pen to paper on a permanent deal with United on Saturday, Wallace revealed just how pleased he was to be back.
And despite interest from other clubs, when the defender learned of United's interest, there was only one place he was going to end up.
"It's brilliant to be back. All the lads have been brilliant since I've come in, and it's like I haven't been away to be honest," he revealed.
"I feel Scunthorpe had the edge, being here on loan, and I really did enjoy my time. So it was quite a straightforward decision in choosing to come back to Scunthorpe.
"I didn't want to be recalled to be honest, I was really enjoying my time playing regular football.
"I understand why they called me back, with a change of manager. But I was a bit gutted I couldn't stay for a bit longer."
