Manchester United boss Jose Mourinho is furious going into the new season without a new centre-half signing.

The Daily Mail says he kept his cool in front of the media ahead of Friday's Premier League opener against Leicester, but privately he was said to be angry and frustrated.

United were prepared to break the world transfer record for a defender and spend up to £100m, but Old Trafford executive vice-chairman Ed Woodward could not deliver a big buy.

After a summer spent airing his grievances from Michigan to Munich, Mourinho turned up on Thursday with his game face on.

Manchester United kick off their Premier League campaign at home to Leicester City on Friday night and even Mourinho knew it wasn't the right time to be griping again.
