"Luke did brilliantly last season in the Premier League and he did enough to warrant and deserve an England call,"

"We were really pleased with him in the summer at the World Cup. We felt he did really well against Costa Rica on his full debut.

"United fans have got to understand - and this is not the boy's fault - that when you sign someone at that age for £27m, you don't get perfection straight away but you have to give him time and space to develop. Luke will need time to settle in, as any 19-year-old boy would coming to Manchester.

"I am expecting he will do well this season but you will see a really quite fantastic full-back in 18 months to two years. When he matures and gets used to the club and settles into the environment and understands the expectation he will blossom.
