Score: Barcelona 3-0 LevanteScorers: Lionel Messi 12' (one-two with Jordi Alba), Luis Suarez 38' (brilliant finish off a Sergi Roberto cross), Paulinho 93' (finish from close range after some Messi magic)Barcelona moved to 48 points (9 above Atletico, 11 above Valencia and a whopping 17 above Madrid - who have two games in hand to be fair) with a routine win over sinking Levante and here are the five key talking points from the match.#5 Marc-Andre Ter Stegen has made Barcelona a better teamTer Stegen flies through the air in training... he's been Superman on the pitch, too.The inimitable Sunny Sagar recently named Marc-Andre Ter Stegen the best goalkeeper in the world, and as he showed against Levante Sunny was dead on in his assessment. Levante attacked with intent - noticing that a centre-back pairing of Javier Mascherano and Thomas Vermalean isn't exactly Maldini-Baresi-esque and they created plenty of chances, but every time they broke into the box, the German stood tall.Some of the saves were comfortable, some were spectacular but at no point in time did he look like he was going to get beat. This brilliance permeates through the entire team and gives them a confidence that is irreplaceable.No team can move from good to great without a great goalkeeper, and in ter Stegen, Barca certainly have one.
