The Foxes need four wins from their remaining six games to confirm the most unlikely of Premier League triumphs after a fourth straight 1-0 win, the slim but effective victory over Southampton last weekend.That extended their advantage to seven points ahead of second-placed Tottenham Hotspur and 11 ahead of Arsenal, in third. After their trip to Sunderland, Leicester face home games against West Ham, Swansea and Everton and visit Manchester United and Chelsea.However, such a lead has been squandered before. In the 2011-12 campaign, Manchester United led by eight points with seven games left and lost the title on goal difference, to Manchester City.So a win at troubled Sunderland is crucial ahead of two difficult away games. The home side remain in the bottom three, now four points behind 17th-place Norwich.The Black Cats, indeed, have drawn their last four league games and have won just once – at home to Manchester United – in their last 10. Four of their six wins this season have come at home.Leicester, meanwhile, have scored 29 goals on the road, the equal best with Arsenal, while they have won 10 on the road, the best in the Premier League.When the teams met in August, at the King Power Stadium, Leicester led 3-0 after 25 minutes and went on to win 4-2. But their record in the Premier League at Sunderland is poor, with three 0-0 draws and two defeats.Sunderland’s only injury victim is Duncan Watmore. Leicester, meanwhile, have one doubt, over Jeffrey Schlupp.
