Wolves promoter Chris van Straaten has made a fresh attack on his under-achieving team ahead of Friday's Elite League trip to Coventry.

The Monmore chief was furious after Monday's home defeat against Eastbourne and is making his feelings plain.

"I will never wash my dirty linen in public but the riders have been told in no uncertain terms that I expect to see an improvement," van Straaten said.

"We have to sort out our mechanical gremlins," he added.

Christian Hefenbrock will again be missing from the Wolves team through injury, with the club using rider replacement.

Freddie Lindgren and Niels Kristian Iversen returned from the World Cup in prime form, but they will be hoping for more help from their supporting cast.
