Daniel Sturridge and Philippe Coutinho are Liverpool's two most important and talented players. I don't really think this can be debated, especially after their performance against Aston Villa on Sunday. The two were reunited once again after both have dealt with injury issues all season. The chemistry between them is apparent for everyone to see. This video does a great job of highlighting it:
The dynamic duo were up to their old tricks against Villa making it tough on their back line all match with their movement. Liverpool's first goal of the match was a direct result of the two's work as Coutinho found Sturridge with a perfect cross to head home. It was a sign of things to come as the partnership between the two dynamic players was dangerous throughout their time on the pitch together.
Liverpool need both players healthy and in-form to have consistent success this season. Now that both are back, perhaps we'll get to see the real Liverpool take flight under Jurgen Klopp.
