London: Leicester full-back Danny Simpson admits the champions' struggles this season have been a shock to the system. The Foxes are just a point above the Premier League relegation zone after Sunday's 3-0 defeat to Manchester United. It was their fourth straight loss – with Claudio Ranieri's side yet to score a league goal in 2017 – and Simpson conceded the Foxes have found this season harder than expected, but they are fully behind Ranieri.
