David Moyes calls 2014/15 Premier League the 'poorest I've seen in a long, long time' after English teams fail again in Europe

Former Everton and Manchester United boss David Moyes believes failure in Europe has exposed declining standards in the Barclays Premier League.

Moyes is manager of Spanish side Real Sociedad, a job he took up in November.

He has been linked with a return to England with West Ham, where Sam Allardyce remains in charge, but appears comfortable in La Liga.

While Spanish sides have flourished in Europe this season their Premier League counterparts have struggled, with none left in the Champions League or Europa League after Arsenal, Manchester City, Chelsea and Everton bowed out this month.

'I think this year you'd have to say it's probably the poorest Premier League I've seen in a long, long time.

'Maybe we do go over the top and recently we have maybe talked up the Premier League more than what it's actually been. There's other leagues which are certainly now comparable.'

Moyes expects to return to the Premier League, but not in the near future.

'I think someday I will,' he said. 'I've left when I didn't expect to be leaving but what I've taken on is a great job.

'I love working in Spain.'
