Michael Appleton believes the crucial goal at Millwall should not have stood.
Dany N’Guessan struck with nine minutes left at The Den this afternoon to condemn Pompey to a 1-0 loss.
N’Guessan floored Hayden Mullins before dispatching a finish past Stephen Henderson.
Appleton thought Pompey should have done better from a defensive perspective, although he felt there was a push on Mullins.
He believed his team looked largely comfortable before the strike – although they needed a greater threat going forward.
Appleton said: ‘It was a goal we didn’t think should have stood.
‘I thought our approach play was good in the first half.
‘We just lacked a bit of cutting edge.
‘That will come but their goal was a concern.
‘I thought we were comfortable until the goal.
‘We kept going until the end, though.’
