Millwall boss Jackett impressed by Bolton striker Ngog
Jackett was full of praise for the French striker, who worked hard in a lone front role and scored the crucial second goal to seal his side's passage into the quarter-finals.
"Ngog played up front on his own and made the ball stick too many times for me," he said.
"Top players like that are good when they get their body in the way and don't give the ball up. The first pass when they get the ball like that secured them possession so many times and it's something we'll have to learn from."
