London, April 8 Kasper Schmeichel says Leicester’s rock solid defence is the secret to the shock leaders’ remarkable charge towards a fairytale Premier League title. Claudio Ranieri’s side are within touching distance of becoming the most unexpected champions in English football history as they head to struggling Sunderland on Sunday and Denmark goalkeeper Schmeichel has no doubts he and the four men immediately in front of him will lay the foundation for another priceless victory. Chelsea captain John Terry this week named seven Leicester players in his vote for the PFA’s team of the year and three of those nominations were for Schmeichel and the club’s centre-backs Wes Morgan and Robert Huth. That trio, combined with full-backs Danny Simpson and Christian Fuchs, have proved an impenetrable obstacle to opposing forwards as the pressure of the title race has mounted, with Leicester grinding out five 1-0 wins in their last six matches. “We defend as a team, we are tough to break down. They are an absolute privilege to play behind, those boys,” Schmeichel said. “They throw their bodies in the way of everything and give us the best opportunity to go and win games.” If the Foxes win at the Stadium of Light they will open up a 10-point lead over second placed Tottenham, who will then have to beat Manchester United later on Sunday to have any chance of remaining in the hunt. Tottenham have no margin for error after last weekend’s draw at Liverpool, which featured an exquisite equaliser from Harry Kane but also the frustration of failing to finish off the Reds. Kane’s 22nd league goal of the season set a new club record in the Premier League era, but the England striker would happily swap personal plaudits for a title winners’ medal and he is determined to keep hunting the Foxes right until the end. Arsenal, in third place, make the short trip across London to face West Ham knowing they must win to maintain their slender hopes of a first title since 2004. The Gunners are 11 points behind Leicester with a game in hand and, despite successive victories, boss Arsene Wenger is as focused on securing a top four finish — they are currently five points ahead of fifth placed Manchester United and seven in front of West Ham — as he is on an unlikely title charge.
