<text>  Scotland are clutching at positives in their bid to avoid the Six Nations wooden spoon, with centre Mark Bennett calling on his side to unsettle Ireland in next weeks final round. Defeat at Twickenham to title-chasing England on Saturday leaves Scotland without a win from four games and with victory over Ireland, who are bidding to retain the championship, required to avoid a Six Nations whitewash for the second time in four years. Ireland have lost on their last two trips to Murrayfield - in the August 2011 Rugby World Cup warm-up and the 2013 Six Nations - while Scotland avoided the wooden spoon in 2010 by winning in Dublin.

Bennett went over to score a first half try for Scotland under pressure from Englands Dan Cole . Bennett, who scored a first-half try at Twickenham, said: We really need to go into the week knowing that we can win. The whole week is about preparing to win. Weve got to go out next Saturday and get the win. Getting the win next week is huge. It would put us in a better position in the tournament and a better position to build on come World Cup time. Our performances have been a lot better than results have shown. With the way that weve played in three out of the four games - the Italy game being a bit of a blip - I wouldnt have expected us to be bottom. Were playing the way we want to, were starting to create opportunities. Its not going to be a negative, going into the game thinking oh no we cant come away with the wooden spoon. Its more were coming into the game to get the win. Ireland have been playing a really hard, tight game of rugby, very disciplined, putting in great kicks, contesting in the air, squeezing things. Weve got to just try to break the mould and run them ragged. England captain Chris Robshaw lifts the Calcutta Cup after England beat Scotland 25-13 at Twickenham . George Ford was among those to go over for England earlier in the second half to put them back in front . Nowell crosses over to score Englands third try of the evening at Twickenham to send Scotland to defeat . Scotlands wait for a first Twickenham win since 1983 goes on. Vern Cotters side took a half-time lead in the Calcutta Cup clash, but failed to score in the second half as England won 25-13. Bennett acknowledged Scotlands front-line defence was not at its best against England, but feels improvement in the scrambled, less structured defence and a reduced penalty count are signs of progress. The Glasgow Warriors centre insisted Scotland must not dwell on what has already happened as they bid to end the tournament on a high. Its disappointing, but youve got to look at why its disappointing, he said. Its our own downfall. Weve made too many errors and penalties in the past. But its a case of this is the problem, this is how we fix it, lets move on.
