Dai Greene celebrates winning the 400m hurdles in Barcelona at the weekend
Wales' European 400m hurdles champion Dai Greene says winning gold at the Commonwealth Games in October will be tougher than his triumph in Barcelona.
The Swansea Harrier led a Welsh one-two at the weekend with Rhys Williams taking silver in the Catalan city.
But on 2010 times, Williams would trail seven places behind Greene at the 2010 Delhi Commonwealth Games.
Greene said: "We'll both be challenging for medals and it will be a little bit tougher than it was at the Europeans."
Greene clocked a personal best time of 48.12 seconds in Barcelona with Williams second in 48.96.
But according to International Association of Athletics Federations (IAAF) rankings, this year Commonwealth rivals from the Caribbean, South Africa and Nigeria have run faster than Williams.
I fully expect the winning time might be a sub-48 - that's what it's going to take to win the gold medal in my mind

They are Dominican Republic's Felix Sanchez (48.17), Trinidad's Jehue Gordon (48.47), Jamaicans Leford Green (48.47) and Isa Phillips (48.68), South African LJ van Zyl (48.87) and Nigeria's Amaechi Morton (48.94).
Greene says those standards ensure what lies ahead in India will make for compelling competition.
He said: "I fully expect the winning time might be a sub-48 - that's what it's going to take to win the gold medal in my mind.
"There are South Africans who have run 48s and 47s in the past and the Caribbean countries - there's a lot more strength in depth there in the Commonwealth than there is in Europe.
"There are more people running sub-49 and sub-48.5. There are some Jamaicans knocking out some great times so it will be a lot tougher there.
"I think I can go two or three-tenths faster at the most. It's just a case of getting it right on the day, really.
"With my event there are so many different variables that can go wrong, it's just a case of practice makes perfect and the more races I do, the more chances I'll get of getting a personal best.
"Hopefully I can go to the Commonwealth Games and produce a performance like I did on the weekend.
"That should bring home a medal, really. I'm basically just trying to prepare for that for the next 12 weeks."
Beyond that though, Greene - who finished seventh at last year's World Championships in a time of 48.68 and is sixth in this year's world rankings - is confident he can challenge for a medal at the London Olympics in 2012.
"I am not that far away," he told BBC 5 live. "Silver and bronze at the Worlds last year were won in similar times to what I am running now [American Kerron Clement took gold in Berlin in 47.91, with Puerto Rican Javier Culson winning silver in 48.09 and American Bershawn Jackson bronze in 48.23] .
In a couple of years I would like to think I could drop half-a-second or so
"I am pretty sure in a couple of years I can run a bit faster again and that will put me in a better position to win a medal in London.
"There are always little areas to improve. With my event no race is ever perfect. There are about 160 steps you have to take and they are all calculated beforehand - where each step is going to be, what part of the lane it is going to put me in, and what leg I am going to take each hurdle with.
"I think I could have gone a bit faster in the final in Barcelona if I had had some guys pushing me to the line, running 47 seconds.
"I would have gone a bit faster down the home straight and cut the hurdles a little bit finer perhaps.
"I am still learning the event all the time and in a couple of years I would like to think I could drop half-a-second or so.
"That is my target. I am only 24 now, I have only been in the sport a few years and I have got a good coach and support staff around me. I think I can go a little bit faster this year and with a couple more years of training and experience, I think it is possible."
