Stanislas Wawrinka is the 'real deal' says Pete Sampras

Stanislas Wawrinka beat an injury-hit Rafael Nadal to win the first Grand Slam of his career in the Australian Open final in Melbourne on Sunday.

The Swiss, 28, won the opening set and was a break up in the second when Nadal took an injury timeout.

Wawrinka grew frustrated and lost his concentration as the Spaniard returned to court to win the third set.

But the 28-year-old regained his composure to become only the second Swiss man to win a Grand Slam singles title after 17-time champion Roger Federer.

BBC Sport speaks to the experts to assess the new world number three's performance in Melbourne - and his prospects of consolidating his position in the rankings.

To answer that you need to separate his value to United right now from how some might view his broader value in the transfer market.

For all the income they generate, United are a club going through a difficult transition. They are way off the pace in the Premier League and struggling to qualify for the Champions League next season.
