Manchester United interim boss Ralf Rangnick expressed his frustration at more profligacy from his team after the 0-0 draw with Watford at Old Trafford.
Cristiano Ronaldo, who hit a post and had an effort ruled out for offside early on, Bruno Fernandes and Paul Pogba were among those who failed to make the most of opportunities in a contest that saw United create many while bossing possession.
