Paul Robinson believes the team deserved the spoils for their second half performance against West Brom on Saturday after a decidedly patchy display in the first period.
The goalkeeper - who was making the 150th appearance of his club career - stood firm in the face of determined rally by the visitors in the first half, beaten only by Kanu's pinpoint header after 11 minutes.
West Brom were unlucky not to add to this advantage before Stephen Kelly was chopped down by Robinson's opposite number Russell Hoult just before the break and Robbie Keane slotted home the penalty to level.
The team clicked into gear after half-time and Jermain Defoe secured a 5th round tie with Nottingham Forest at the Lane on Sunday with two superbly executed strikes.
"In the first half we were poor," reflected Paul afterwards. "We went in at half-time having performed like we had never played together, but managed to hang in there and we knew we couldn't play as badly in the second half.
"We upped our performance and got a result. We deserved it for our second half performance.
"I'll tell you what, West Brom are not a bad team, we have played them in the league and cup and they have got a bit about them. We have seen their games over the last few weeks and they have been unfortunate."
The Cup theme continues now with Forest looming on Sunday and Paul is expecting nothing other than another tricky encounter.
"It will be another tough game, they are struggling in the league at the moment, but it is a cup game. Hopefully we can get through to the next round."
