Charlton's display in a goalless draw with Scunthorpe at Glanford Park brought a smile to Russell Slade's face.
The Addicks were the better side on the night and almost snatched a late victory, when Johnnie Jackson's superb free-kick hit the frame of the goal.
"I thought it was a really solid performance and we created a few openings, more than them," said visiting boss Slade.
"We played some really nice football, but we didn't quite get the goal that we deserved. It was a really solid away performance against a free-scoring side.
"They hit Gillingham for four and Southend for five at home, but they never looked like doing that tonight, so credit to the players.
"Our attitude, mentality and the way we moved the ball around on their pitch was excellent."
Slade praised defenders Patrick Bauer and Jason Pearce for keeping Scunthorpe's deadly duo of Kevin van Veen and Paddy Madden quiet.
He added: "We were up against two strong strikers, who have been a menace in this division this season and I thought the two centre-backs did an excellent job on them."
Scunthorpe manager Graham Alexander praised the way his side kept going to the end, saying: "They all came off sweating buckets out there.
"It was a real tough game, Charlton are an excellent side. They came with a formation to nullify our threat and they were good on the ball, so I am delighted with my players.
"When you are at the top of the table, people make plans to stop you and that was evident tonight. They made it really difficult for us."
