West Ham United defender Winston Reid admitted relief after their FA Cup win over Bristol City.
Substitute Diafra Sakho broke City hearts with an 81st-minute winner.
"In the first half we were under pressure, which was always going to happen when you come away to these places," Reid told whufc.com.
"They gave a good performance but fortunately for us we kept a clean sheet and Sakho came on and got the goal.
"Obviously we wanted to finish off the game in one go, get a goal and get the win and we did that. Even though we didn't play our best football, we got there in the end and the most important thing is we're in the next round.
"The manager was speaking beforehand about the amount of upsets and we didn't want to be one of them. We did all right and made the most of the opportunities that we created and are now in the hat for the last 16."
