Bolt too hot to handle
Usain Bolt again provided a demonstration of complete dominance as he won the 100 metres at the Diamond League in Brussels.
The six-time Olympic champion eased through in 9.80 seconds with Great Britain's World Championship finalist James Dasaolu eighth in 10.15secs.
The best British performance of the night came from Martyn Rooney, who chased down Borlee in the final metres to claim the 400m.
However, all eyes were on Bolt.
The Jamaican had not enjoyed the most convincing of campaigns before last month's World Championships but he underlined the athleticism and class in Moscow that will see him sorely missed when he retires after the Rio de Janeiro Olympics in 2016.
Bolt won three titles in Russia and did not fully get going until the midway point when he eased away from the field to win ahead of Michael Rodgers of the United States and Jamaica's Nesta Carter, with Moscow silver medallist Justin Gatlin fourth.
Bolt, though, believes he can still eclipse his world record of 9.58 and was clearly frustrated by his start.
He told BBC2: "I definitely can run faster. I started the season pretty poorly and then got an injury and as you get older it is harder to come back from injury. If I had got the better start it would have been 9.70."
Asked if he had enjoyed the season, he added: "Kind of - it was not the best season of my career but the main thing is I finished on top and I dominated."
The prospect of seeing Bolt at next year's Commonwealth Games in Glasgow is a real one although he was not committing.
He said: "I don't know what I am doing yet, my coach makes the decision.
"I would love to go, I would love to get a Commonwealth gold medal to say I have got a Commonwealth gold medal. We will see what happens."
Dasaolu was also disappointed with his start and although he was level with Bolt in the adjacent lane, the Briton made no impact on the race.
He said: "For me it was about executing the start and I didn't do that as well as I would have liked to.
"I gave it my best, but maybe I was a bit distracted. When you look at my goals for the season I wanted to run sub-10 seconds, which I have done twice and I made the final in Russia."
Rooney was part of the 4x400m relay squad in Moscow but failed to qualify for the individual event after a season disrupted by injury.
Tonight he ran a season's best of 45.05 to reel in home favourite Jonathan Borlee, with both men given the same time but the Briton awarded the victory.
He said: "I'm really happy to win here. I've been ill for a week-and-a-half but to finish with a season's best, I'm happy with that.
"It's a bit late but gives me something to build on."
Christine Ohuruogu was not among the challengers as she finished fifth in the 400m in 50.95 in a race won by American Natasha Hastings.
While it was a flat end to the year for the Briton, ultimately she won the big one having edged out Amantle Montsho by inches for the world title in Russia.
The Londoner said: "I thought it would be quite nice to keep the momentum going and I knew I had some good runs still in me.
"But it's mentally tough and a bit harder to get back up after what has happened. But I did want to come out and run fast, but I wasn't quite sharp enough. But I'm cool."
World bronze medallist Tiffany Porter was fourth in the 100m hurdles in 12.78.
Rhys Williams was eighth in the 400m hurdles in 50.13 which was won by world champion Jehue Gordon.
Chris Clarke (20.45) and James Ellington (20.52) were seventh and eighth respectively in the 200m.
Warren Weir, world silver medallist behind Bolt, won in 19.87.
Andrew Osagie was eighth as Mohammed Aman ran the fastest 800m of the year in 1min 42.37secs, the Briton 2.97secs adrift, likewise Luke Cutts in the pole vault (5.50m) while Julian Reid was 10th in the triple jump (15.73).
Hannah England was fifth in the 1,500m in 4:08.31 and Eilish McColgan eighth in the 3,000m steeplechase in 9:39.79.
Triple Moscow champion Shelly-Ann Fraser-Pryce set a meet record of 10.72 to win the 100m and the Diamond Race by some distance.
