EVERTON assistant manager Steve Round praised the team's fighting spirit after they saved themselves from a League Cup exit with less than two minutes to spare at home to West Brom.
With two minutes remaining, the hosts were trailing to Chris Brunt's second-half penalty, but Marouane Fellaini volleyed home from the edge of the box to take the tie into extra time.
And, just before the end of the first additional period, captain Phil Neville produced a brilliant 25-yard strike to clinch victory.
"At Everton you go right to the death, that is one of our strengths with the spirit we have got," said Round.
Cardiff manager Malky Mackay hailed his team's battling qualities after they continued to do it the hard way in the League Cup.
The Bluebirds sealed their passage into the fourth round following a dramatic penalty shoot-out victory over Championship rivals Leicester.
Mackay's men scored all seven spot-kicks, including Paul Quinn's well-taken winner after Gelson Fernandes had blazed over for the Foxes.
The win puts Cardiff, who also needed extra-time in previous round successes over Oxford United and Huddersfield Town, into the last 16 of the competition.
Southampton manager Nigel Adkins hailed the performance of substitute winger Adam Lallana, whose goal moments after coming on earned Saints a 2-1 win over Preston.
The former England Under-21 international made his presence felt within 90 seconds of his appearance, stooping low to finish off a move he began.
Aldershot, Arsenal, Blackburn, Bolton, Burnley, Crystal Palace, Manchester United, Newcastle, Stoke and Wolverhampton advanced to the fourth round two nights ago.
The fourth-round draw will be made September 24, with the games played the week of October 24.
