Manchester United defender Jonny Evans is adamant that after working with Luke Shaw the teenage starlet has all that it takes to become the best left-back in world football.
Shaw is still waiting to make his competitive debut for the Red Devils after his start to the season was ruined by a hamstring injury, but Evans saw enough during United's trip to America to assert confidently that the £27m deal will prove to be an absolute snip for Louis van Gaal's side in the long-term.
Evans is quoted by the Daily Star as telling United Review: "I had the chance to work with Luke in pre-season and there is no doubt he is going to be the best left-back in the world."
Shaw still waiting to make impact
It's been far from a dream start to life as United player for Shaw, with his fitness called into question by Van Gaal long before that hamstring injury stopped him taking part in their first three Premier League games.
The former Southampton standout looks tailor-made for Van Gaal's preferred 3-5-2 formation, but quite unfortunately missed out on the chance to show just that against Swansea City, Burnley or Sunderland in the first month of the season.
Shaw was back in contention for last weekend's 4-0 win over Queens Park Rangers but had to settle for place on the bench, with Van Gaal switching to a diamond 4-4-2 system and preferring another summer signing in Marcos Rojo at left-back.
Rojo made debut at left-back
Rojo has a wealth of international experience and will provide stiff competition for a starting spot at left-back all-season long, unless he's moved inside to operate in the centre of defence.
Evans was also asked about Rojo and offered another glowing reference for his new colleague, although this one didn't come with first-hand training experience to boot.
The Northern Ireland captain said: "I watched Marcos at the World Cup and thought he was excellent for Argentina whether he played at left-back or left wing-back, and he can play centre-back too.”
Decisions over how best to utilise both Shaw and Rojo will provide Van Gaal with yet another interesting selection dilemma this season, but it's clear that Evans feels the England international will force his way into those plans if he matches application to a wealth of talent in the next few months.
