Rio Ferdinand slams England defender Kyle Walker for criminal mistake against Tunisia
Gareth Southgates England enjoyed a bright start to their opening World Cup group match and captain Harry Kane poked the Three Lions ahead on 11 minutes.
England then wasted a number of chances through Jesse Lingard, John Stones and Raheem Sterling before Tunisia were offered a glorious chance to equalise.
An innocuous cross from Dylan Bronn floated across Englands box but Walker was penalised for blocking the run of Syam Ben Youssef with his elbow.
Ferjani Sassi stepped up and slotted his penalty past goalkeeper Jordan Pickford as Tunisia went into the break level.
Speaking to BBC at half-time, Manchester United legend and former England defender Ferdinand said: If Kyle Walker is positioned correctly, he doesnt concede a penalty.
A centre-half facing his own goal when a ball is coming into the box is criminal.
Martin Keown, the ex-Arsenal and England star, added: There cant be any real complaints from Walker and its an outstanding penalty by Sassi.
I thought Pickford might have got there but his fingertips just cannot keep it out.
Despite Walkers blunder, England were the dominant side in the opening 45 minutes and Ferdinand was generally pleased with the display.
The vast majority of the play from England was very positive, they went after Tunisia, the passing was crisp and varied, he said.
They got the goal and we thought they would push on.
Weve created so many chances, at this level you take them or you are punished. We should have scored three or four.
