Steven Caulker hoping move from Tottenham to Cardiff City can seal place in England World Cup squad It wasn't that I wanted to leave Tottenham but I am at a stage in my career where I want to play regular football. Spurs have three fantastic centre-halves and it may have been a case of being fourth-choice this season and not getting as many games as I would have liked. I didn't want to put my career on hold, I wanted to get out and get as much experience as possible and these opportunities don't come around very often. I want to help Cardiff progress as a team and progress myself. Caulker has previous experience of playing in south Wales, having enjoyed an excellent loan spell with Swansea during the 2011-12 season. His move to Cardiff is likely to add some spice to the derby fixtures between the two clubs, but he revealed he has received messages of support from his former team-mates at the Liberty Stadium. "I enjoyed my time at Swansea and the people in south Wales are great so it was a no-brainer to move here," he said. I thank Swansea for that opportunity, it progressed my career, but now I am a Cardiff player and I hope to go above and beyond for them. I spoke to a few Swansea players before their game (against Malmo) last night, I wished them luck and they wished me luck. There are no hard feelings between us as players. It will be fantastic to be involved in the derby, I played in a London derby a few years ago and I am definitely looking forward to this one. Mackay is delighted with the acquisition of Caulker, but made it clear he will not simply ditch the defensive pairing of Mark Hudson and Ben Turner which served him so well last season. "People have to work hard to get in the team and stay in the team," said the Scot. We have a group here who won the Championship by a huge margin which means I have a lot of respect for the players here. It is about bringing quality to the group and that is what we have done.
