The West Yorkshire side are looking to bounce back from a lacklustre performance against Everton at Goodison Park last weekend. Leeds face a huge week of Premier League fixtures, with Sunday afternoon's match against their old rivals followed by a midweek trip to Anfield, with a game against Tottenham Hotspur scheduled for three days later. But Bielsa has been putting his squad through their paces this week in preparation. "We've been working on a lot of things this week - organisation and being more dangerous on the attack," Harrison said. "So hopefully we can show what we've been working on this week." On Sunday afternoon, Elland Road plays host to a Premier League clash between Leeds and Manchester United in front of a full crowd for the first time since 2003. A big day for the fans, but for Harrison and his Leeds teammates, the focus is on earning points. "I think it's just the same, I think it's a very historic game, it's got a lot of history behind it - the rivalry, you know," Harrison told Sky Sports. "It's a massive game for both sides and we're hoping to come out with a win today. "I mean, I'm not really sure what to expect. I'm sure it'll be an exhilarating game, and the fans will bring a lot of energy, which is going to be important. "It's been a long time since fans have seen a game against [Manchester] United and I think everybody's just really excited so I'm excited to see what the atmosphere is like."
