The Lions manager hailed the Irish striker's goal in the 1-0 victory over Wolves at Molineux and said that he was 'really pleased' to see the player score
The Republic of Ireland international struck the only goal of the game on 80 minutes to condemn his former side to a home loss and Lions manager Jackett revealed that he was 'really pleased' to see the striker score.
"It was a fantastic result for us," Jackett told the club's official website. "In the first half we looked flat and lacked energy, but we hung on in there.
"In the second half we grew, you could see the goal coming and I was really pleased to see Andy Keogh score. He had two good goals disallowed at Blackburn on Saturday and was owed one; I was delighted it came for him tonight," he added.
Keogh, 26, signed for Championship side Millwall from Wolves in January 2012 and has scored five goals in 17 league appearances this season.
