The Oaths of the Horatii, Jacques Louis David
“When it comes to surviving in the latter stages of the Champions League, it seems versatility is the key to vitality. One of the most notable things about the four sides that have made it to this season’s semi-finals is that all four have, to a greater or lesser extent, deployed formations and tactical systems that they do not use in domestic competition in order to reach the last four.” (Football Further)
