Dwain Chambers today insisted he had always felt "relaxed" about being picked for next month's World Championships even though he underperformed in the trials two weeks ago.

Chambers - who will contest the 100 metres and 200m in Berlin - suffered a shock defeat at the hands of Simeon Williamson in the 100m in Birmingham.

The 31-year-old Londoner then said he was feeling unwell and withdrew from the 200m suffering from fatigue.

With only event winners automatically gaining selection for the championships, that left his inclusion in the hands of the selectors.

Having controversially returned to the sport 20 months ago, there was a question mark about his inclusion.

One possibility was that up-and-coming sprinters, such as Harry Aikines-Aryeetey, could have been included to give them valuable experience leading up to London 2012.

But the appointment of Charles van Commenee as UK Athletics head coach left Chambers confident of his spot in the Aviva GB team.

Van Commenee, on taking over the reigns at UKA, insisted Chambers would be welcomed back into the fold after serving his two-year doping suspension.
"I was always relaxed about the decision," Chambers said.

"He is a man of his word and I respect him."
Chambers took a week's rest after his disappointing display in Birmingham, which he blamed on tiredness.

"I'm not making any excuses but I was suffering from a lack of energy," he said.

During May and June Chambers clocked up around a dozen races, including 100m and 200m victories for his country at the European Team Championships.

Chambers said: "I was just exhausted, I had too many races. In Birmingham I just wasn't there.
"I'm okay now, I've had 10 days of hard training and I am preparing for Berlin."
