Portsmouth manager John Mousinho told BBC Radio Solent:
“Delighted with the result and we matched it with a really good performance, a really strong performance.
“Take the opening minute or so out of it when Nico saved us – it’s easy to forget that when you come away with an important away victory, you look at that and it was just a moment of us being lax defensively but then I think that maybe sharpened us up a bit.
“After that, I thought for 55 minutes we were excellent, fully deserved the lead, came out in the second half and Charlton make three changes, you might expect a different game.
“But we came out, fully deserved to get the third goal and it went a bit crazy after that. We made a few very strange decisions after that which we hadn’t made but the fact we saw the game out in difficult circumstances is really pleasing.”
