Skipper on the night, Robbie was back in the starting line-up for the first time in 12 matches and marked his return with the second goal in our 4-0 third round replay victory.
Aaron Lennon opened the scoring against the Bluebirds after 26 minutes, Robbie finished from Dimitar Berbatov's assist a couple of minutes later and we were firmly in the driving seat at half-time when Steed Malbranque fired home from 20 yards for 3-0. Jermain Defoe came off the bench to wrap up a good night's work with the fourth 10 minutes from time.
We now face Southend United at home in the fourth round on Saturday January 27, kick-off 7pm.
"The result is the most important thing and we won convincingly in the end, but it was great to get back on the scoresheet again," reflected Robbie. "All the strikers are scoring goals and that's only good for the team.
"The first goal was always going to be important and once we went ahead and then got the second so quickly, it killed them off. The second half was a bit flat but that tends to happen in games like that.
"We're doing well in the cups and we want it to continue. We've a good draw in the next round in that it's at home - no draws are easy, though - and we've avoided another Premiership side. If we can continue the season looks promising."
Robbie Keane was delighted to get back amongst the goals in his first start for over a month against Cardiff at the Lane on Wednesday night.
