Leeds United v Arsenal: We can shock the Gunners - Watt

Sanchez Watt insisted he was ready and willing to knock Arsenal out of the FA Cup after his first goal for Leeds United inspired a ruthless victory over Scunthorpe United.

The winger's 17th-minute strike was the catalyst for a 4-0 win at Elland Road on Saturday, and his performance is set to earn him a second opportunity to face Arsenal – the side who loaned him to Leeds at the start of the season.

Watt was unexpectedly granted permission to turn out against his parent club in United's third-round tie at the Emirates Stadium on January 8 – a game which ended in a 1-1 draw – and he is eligible again for Wednesday night's replay in Leeds.

Watt promised not to celebrate if he found the net in Wednesday's replay with Arsenal but he denied that split loyalties might affect his

desire for an upset at Elland Road.

"I didn't think I was going to be able to play in the first game but when I found out I was, I got myself focused," Watt said. "I knew I had to have a good game – to show people I wasn't holding back and I was giving my all.

"We're going into the game with a lot of confidence and I hope we can win. I want to play to the best of my ability and I want to score. I want to show people that I can be a player and stay in this game for a long time.

"It'll be strange if I score but I'll be feeling good about the fact that I've got a goal against a great team and a great defence. I won't celebrate but inside I'll be happy."

Watt's first goal in United's colours came in his 22nd game for the club, appearances which have been spread over two different loan spells at Elland Road.

His finish from outside the box opened the floodgates against a toothless Scunthorpe side, leading to further goals from Max Gradel and Bradley Johnson before the half-hour.

Watt admitted that his finish was overdue after more than half a season with Leeds, saying: "I'm glad to get one and I've been waiting a long time for it. I should have had a few more by now and I hope there are plenty more to come.

"I've been used in a few positions but the manager wanted me to play in the hole, to get at them and gamble on flick-ons. I did that and I got my goal. It's a big win and we needed it because we've got a big game on Wednesday. We should have a lot of confidence going into that."

United's victory kept them in fifth place in the Championship, two points adrift of second-placed Swansea City, and the result took advantage of points dropped by QPR and Cardiff City.

Leeds were already assured of their win when Davide Somma rounded off the scoring on 89 minutes, his eighth goal of the season.

Grayson said: "When you're 3-0 up early on, you've obviously got a

platform to win the game.

"But we did the other side of the game well because I knew Scunthorpe

would work hard and close us down. We did that to them as well. We took the right options and scored some very good goals."
