When was white winning?

Lev Aronian has won the 2017 Grenke Chess Classic, ahead of a very strong field. His win may have been helped by the fact I did not give him the 'kiss of death' by tipping a win for him, but it was more likely to be due to his strong play.
One of his early tournament victories was against Maxime Vachier-Lagrave in a game that on the one hand exemplifies modern chess, but on the other, one I found difficult to get a handle on. Following the 'pawn structure be damned' approach, both players found themselves with rooks and bishops after 14 moves, and one open file to fight over. To my untrained eye this wasn't enough for either side to claim an advantage, but after another 20 moves, Aronian was able to force one of his pawns to f5 and Black's position collapsed. At first I thought Black must have made one big mistake, but going over the game it seems that it was more a succession of little ones that caused his defeat, culminating with him losing control of f5.
