Of all the statistics gathered by Manchester United's backroom staff during the first two weeks on tour, one in particular stands out.
The high-intensity work that the players have been subjected to so far in Perth and Singapore is 50 per cent up on the corresponding period last summer when Jose Mourinho put his squad through their paces.

It was evident in Saturday's 1-0 win over Inter Milan at the National Stadium in Singapore. Young Mason Greenwood deservedly grabbed the headlines for scoring an excellent goal — his second off the bench in consecutive games — but Solskjaer was more delighted with the overall work ethic of his
