'I think with playing for Wales the Champions League is probably going to be the highest level I will be playing at the moment,' he said.

'And I think that is the most important thing now for us this season.

'Personally I think it was a fantastic night and we did prove to Europe that we can compete with the big boys.'
Bale was also nominated for the PFA Young Player of the Year, but that award went to Jack Wilshere of Arsenal.

'I have to keep it up now and hopefully we can win something this year.'
Arsenal were held to a 1-1 draw by Liverpool, but Wilshere said: 'I don't think the title has gone.
