Former England goalkeeper Nigel Martyn believes David de Gea's upturn in form has been the catalyst behind Manchester United's resurgence as odds-on favourites to retain their Barclays Premier League title.
Martyn, who made 23 appearances for England between 1992 and 2002, thinks the 21-year-old goalkeeper has rediscovered his confidence following a tough start to his career at Old Trafford.
He said it had naturally taken him "a little bit of time to adapt" but added: "Working at it as he obviously is, it's bearing fruits now. His form has coincided with Manchester United's form at the end of the season and it's on that basis, a good defence and a good goalkeeper, that league titles are won."
