The Hammers have been awarded just one spot-kick this term, and have not been given one away from home in the league in the last four seasons.
They were denied a victory at Chelsea on Saturday after the hosts snatched a 2-2 draw with a late Cesc Fabregas penalty. Referee Robert Madley pointed to the spot after Ruben Loftus-Cheek went down under Michail Antonio’s challenge, although any contact appeared to be outside the area.
Sullivan said: “What hurts me is we get no such marginal calls our way... we have not had an away penalty in the league in four seasons and we have had less penalties in four seasons than any team in the Premier League.”
Mark Noble scored West Ham’s solitary spot-kick this term, at home to Bournemouth in August. Current league leaders Leicester have won 10 this season alone.
The club awarded the most penalties in the Premier League over the last five seasons are Manchester City.
City have been awarded 34 spot-kicks since the start of the 2011/12 campaign, leaving them ahead of Liverpool (32), Chelsea (31) and Manchester United (31) at the top of the pile.
Remarkably, 82% of City’s penalties (28) have come in front of their own fans at the Etihad Stadium, with only six on their travels. Chelsea (74%) and Manchester United (61%) have also had the majority of their penalties at home, though Liverpool, Arsenal, and Tottenham have all won more spot-kicks on the road.
Man City 34 (28 home, six away), Liverpool 32 (15/17), Chelsea 31 (23/8), Man Utd 31 (19/12), Stoke 24 (10/14), Everton 21 (13/8), Tottenham 21 (9/12), Arsenal 20 (9/11), West Brom 19 (12/7), Sunderland 17 (8/9), Swansea 17 (11/6).
