Arsenal legend Sol Campbell feels the Gunners have shown the \"guts\" needed to finish their Premier League season on a high. Thomas Vermaelen swept home a dramatic stoppage-time winner to beat Newcastle United on Monday night, which was a fifth straight victory for Arsene Wenger\'s side, having come from behind four times in a row. Arsenal have surged back up into the UEFA Champions League places and are now just a point behind arch-rivals Tottenham Hotspur, whom they beat 5-2 on 26 February. It is a series of displays, also including a 3-0 win over AC Milan in Europe which went some way to making up for the first-leg 4-0 defeat in Italy, which have left Campbell believing his old club can end a difficult campaign with a positive finish. \"The lads have shown a lot of spirit. You have to get a bit of the rub of the green, but that tends to come when you start being bolder on the pitch,\" former Gunners captain Campbell, part of the 2003/04 \'Invincibles\' side, told Arsenal Player. \"Gamble on your skill, gamble in the box, gamble in thinking: \'I am going to try this\'. Start gambling your talent, basically. The more you bust a gut to win, the more you are going to see the crowd feed off that. \"You make your own luck, and against Newcastle there was a little deflection for the winning goal and the ball came to Vermaelen, but he was there because he busted a gut to get into the box.\" Campbell, 37, returned to his old club for a short spell during 2010, and feels current skipper Robin van Persie is leading by example. He said of the 33-goal Dutchman: \"Robin van Persie is flying and banging in goals left, right and centre. Everyone is starting to gel and realising what it means to play for Arsenal. \"That level of confidence and class is what they should be aiming for all the time. Sure, sometimes you won\'t reach that level but you have to work out how to grind out a result, or shut the game down. That is a learning curve.\" Campbell won two Premier League titles and three FA Cups with Arsenal after moving from Spurs in 2001. The former England centre-half feels Wenger\'s latest generation can deliver some long-overdue silverware if they continue with the same work ethic. \"Hard graft and talent go hand in hand. There are not many top players around the world who don\'t work on their skill,\" Campbell said. \"Being responsible on and off the field is crucial. Everyone likes to have a great time but it is about realising: \'I want to win the league or the cup, so I have to knuckle down here\'. You have to make sure you don\'t waste your career and actually work hard and be a part of history.\"
