Cardiff City manager Malky Mackay said Cardiff City were "a match for West Ham" in their 2-0 defeat to the Hammers. It was the Bluebirds' first ever game in the Premier League, but Mackay said the loss was not "a lesson" for the Welsh side.
"We knew before the game we had to be clinical. It's choices in that final pass, that final decision," he said.
"We had a three on two and Campbell decided to have a strike at target instead of sliding Bellamy in. It's about decision making, I don't think it's about learning lessons.
"We knew exactly what we were coming to, we knew what our game plan should be today and for vast parts of the game we certainly had control over a lot of the ball."
Cardiff City began life in the Premier League with defeat, after losing 2-0 away to West Ham United.
The Bluebirds enjoyed more possession than the home side over the 90 minutes, but it was Joe Cole who put the Hammers ahead with a 13th minute strike, before Kevin Nolan found the back of the net in the 76th minute.
Cardiff City will be hoping their home fans can give them a boost in their next league fixture, when they host Manchester City on 25 August.
Cardiff City's first 45 minutes in the Premier League did not end in the way they would have hoped. The Bluebirds returned to the dressing room at half time losing 1-0 to West Ham United, after Joe Cole scored in the 13th minute.
