Price tag problems at United

Manchester - Juan Mata and Angel Di Maria are the two most expensive players in Manchester United's history, costing a combined £97 million last year as the club looked to regain its status as England's top team.

So far, they aren't living up to their price tags, and there's a chance neither will be in United's lineup when the team visits Newcastle in the English Premiership on Wednesday.

Mata, bought for £37.1 million by David Moyes, has mainly been used as a substitute by new manager Louis van Gaal this season despite a decent scoring record when he has started for United. A World Cup and European Championship winner with Spain and twice Chelsea's player of the year, the playmaker is a forgotten man at Old Trafford these days.
