Gary Neville is not convinced Cristiano Ronaldo will propel Manchester United to the Premier League title this season.
The Portugal star completed his sensational return to Old Trafford in a £19.8million two-year deal on deadline day, 12 years after leaving the club for Real Madrid.
But the former United defender is uncertain if the five-time Ballon d'Or winner will be enough to claim the club's first league title since 2013.
'It strengthens Manchester United enormously,' Neville told Sky Sports News.
