#3 David de Gea
If David de Gea continues to improve and develop at his current rate, he could soon find himself as the best goalkeeper in the world. The Spaniard famously received an incredible amount of criticism when he first arrived in Manchester as a 20-year-old. Analyst's argued that he was too weak, and many predicted that de Gea would never adapt to the English game. It took him less than two years to prove his doubters wrong. Despite his club's poor performances over the past five seasons, the 27-year-old has made the Premier League team of the year 5 times, and de Gea has also established himself as Spain's first choice. After his long-rumored move to Madrid never came to fruition, de Gea now looks to be Manchester United's most important player for years to come.
