KENNY Jackett admitted he had made a mistake in substituting Shaun Batt in the 61st minute of Millwall's 1-0 defeat to Nottingham Forest on Saturday.
Lions fans voiced their frustration after Batt, who had battled admirably in a lone role up front, was withdrawn just after the hour mark and Jackett conceded afterwards their reaction was "justified."
He said: "I had my thinking in terms of managing Shaun because he's never quite been a 90-minute player. In hindsight I should have probably given him a go in a two for ten or 15 minutes.
"That is with hindsight at the end of the game. I have been pleased with Shaun since he came back from Leyton Orient – whether playing with a partner or as a lone striker.
"There's a misconception about playing one striker because it's not necessarily easier with two. You can throw as many people up there but the ball won't get to them if you don't control the midfield.
"But I have got to say the crowd's reaction to that subsitution was probably justified because Shaun did deserve a little bit longer in a different formation or combination."
