Juan Antonio Pizzi has praised his Valencia side following the goalless draw with Sevilla in La Liga on Sunday.
The visitors were forced to play a large chunk of the second half with 10 men after Ricardo Costa was dismissed for two bookable offences, but Pizzi's team held on for a point.
"The second half is difficult to analyse. To play that long without a man down is very difficult," he told reporters at a press conference.
"They had a lot of the possession and it was clear that at some point they could score a goal. We had the character and the integrity to endure though, and withstood their attacks very well."
The draw means that Valencia are now unbeaten in their last five league matches.
