5. Philippe Coutinho – Liverpool
Liverpool's decision to spend £8.5m on Inter Milan playmaker Philippe Coutinho was undoubtedly risky – but the Reds' leap of faith has paid dividends.
The Brazilian is able to play passes that are nigh-on impossible to spot from the stands, while his link-up play with his teammates at Anfield has often been sublime.
Still only 21, Liverpool have a real gem on their hands.
