5. Cristiano Ronaldo - 84 Goals
From a man who ground out the Premier League goals across a mammoth career to one who shone brightly over a short period - Cristiano Ronaldo is in at number five on our list. The Portuguese superstar hinted at the magnificent form he would soon be showing for Real Madrid by bursting into life at Old Trafford after a season or two settling in. In 2006/07 Ronaldo broke the 20-goal mark for the first time in his career and he didn't look back; in his last two seasons for the Red Devils he hit 50 league goals. Astonishingly, he would move up a gear when he joined Madrid in 20095.
