We scored 4 goals without Neymar and Pedro in the starting lineup.
Sure. I'm not saying we'd always lose if one of MSN went down, but the chance of losing points in that situation is much higher without Pedro. Also, as for scoring 4 goals today, a good deal of that has to do with Messi being in a form that he won't be in every match. If Messi plays like he did in the first half, then yeah, we'll be fine no matter who's up front with him. But even Messi won't always play like that.
