#4 Reminder: Luis Suarez is still really really good
Barcelona have not had Lionel Messi's services for the past two weeks, but another South American has compensated for the Argentine's absence. Suarez has been absolutely sensational in Messi's absence, and he was the star against Rayo as well.
The Uruguayan opened the scoring early on and then slotted the winning goal in stoppage time. He struck the woodwork as well and did not stop running till the end, which enabled him to clinch the points.
A physical decline is natural for Suarez owing to his age, but many were writing him off completely when the season began. He has roared back in recent weeks, and his hat-trick against Real Madrid last weekend was an utter masterclass. Simply put, Suarez is still very good, and he will soon have his partner in crime beside him. Beware, LaLiga defences.
