England beat Tunisia 2-1 in their tournament opener but their boss was bemused by a number of contentious penalty decisions
Gareth Southgate believes it will be an "interesting" World Cup if penalties akin to the one England conceded against Tunisia continue to be awarded.
England claimed a 2-1 win over Tunisia in their opening Group G encounter in Volgograd on Monday, but looked set to have to settle for a draw after Harry Kane's opener was cancelled out by a contentious spot-kick from Ferjani Sassi.
Sassi converted from 12 yards after Kyle Walker was penalised for catching Fakhreddine Ben Youssef with his arm, which the defender disagreed with after the match.
