Chris Powell left Hillsborough a frustrated manager on Saturday after watching Charlton lose 2-0 to struggling Championship side Sheffield Wednesday.

Despite making a bright start, the Addicks fell behind to a volleyed effort from Rhys McCabe in the 20th and their fate was sealed when Manchester City loan player Jeremy Helan made it 2-0 in the fourth minute of injury time with a strike from close range.

Charlton were convinced they should have had a penalty when Yann Kermorgant tangled with Anthony Gardner in the 37th minute, and Powell's protests saw him red-carded by referee Gary Sutton.

The Addicks boss said after the game: "There were a number of incidents that angered me during the first half and I went to the referee at half-time and asked him about a penalty we didn't get. There was a goal ruled out for offside which was actually onside and there were also a number of fouls on my players.

"I was asking for consistency and fairness but I didn't swear at the referee or point at him."

To make matters worse for Charlton, there was a second-half booking for Lawrie Wilson which took him to five yellow cards for the season, ruling him out of the Boxing Day game against Ipswich at The Valley.
