'We need to get into the mindset that we're a big club and that we can challenge.' Martin O'Neill believes Sunderland must see themselves as 'a big club' as they look to push onwards and upwards. The Black Cats take on one of the game's giants this weekend as Liverpool visit Wearside for a key Barclays Premier League clash. O'Neill wants to see his side pushing out of the middle of the pack and challenging in the upper reaches of the table. And he says all on Wearside must believe that further progress can be made as the upwardly-mobile Black Cats aim to push on. Speaking about the pressure Liverpool's players and staff often find themselves under to get results, he said: "I think that goes for the other big clubs too and we want to try and push ourselves into that position. "This is a big club, and sometimes you just have to remind yourself just how big and passionate it is. "If we need any proof of at all of that, just look at our supporters on Sunday. They made themselves heard, even from miles away. "That's what we've got to get into - the mindset that we're a big club and that we can challenge. "I'm not saying we've reached that standard yet. We haven't - there's no question of that. "There's no doubt that the top sides are better than the ones below, and it's been a real scramble. "We're still scrambling at the moment, but we're playing with plenty of desire and being supported with plenty of desire Great finally a manager that can and will take us where we haven't been for a long time
