"When ARC closed down Hereford and Folkestone, for which there are no re-opening plans, it was the first time any long-established track had been shut in over 30 years.

"The Hereford decision was especially controversial as it followed a confusing dispute with the local authority over the lease, which ARC then refused to release.

"This news, a notable boost to an area with a high number of trainers, comes as ARC's new management works to shake off its "nasty racecourse group" image gained at least partly because of the original closures."

However, there are currently no plans to reopen Folkestone racecourse in Kent.

Norwich's new defender Timm Klose: "I always wanted to play in the Premier League. I had a good talk with the coach so in the end it was an easy decision.

"It's important for Norwich to stay in the league. I know what it's like to be down in the table and that makes a difference.

Norwich's new striker Steven Naismith: "The manager knows what my attributes are. He wants me to play like I have done for Everton

"I'm looking forward to it. I've always had to fight, and we're fighting to stay in the league. I want to be part of it.

West Brom manager Tony Pulis reveals he has a big choice to make, whether to pick Boaz Myhill in goal, or the returning Ben Foster, who has recovered from a serious knee injury.

Pulis said: "It's brilliant to have an England international goalkeeper back. Bo has been fantastic. I've got a big decision to make."  

West Brom trio Chris Brunt, Darren Fletcher and Jonas Olsson are doubts for Saturday's match.  

Manager Tony Pulis said: "We have a massive game Saturday against Villa. They're four games unbeaten and have struck a bit of form.

"We will rely on our supporters tomorrow, we will need their help especially with the injuries. They have been wonderful recently."

Saido Berahino will be back in the squad for Saturday's West Midlands derby.

The striker who has been linked with a move away from the Hawthorns in January, missed the midweek FA Cup third-round replay against Bristol City.
