I found 12 clubs who had similarly good underlying numbers but a gap between real and expected goals of at least five. Those teams historically bounced back strongly from their slow starts. Of the 12, 10 clubs finished in a higher league position than they were in at the six-week point; only one finished lower.
This group includes some of the great comeback stories of the last five years. Udinese marched from 20th at the end of Sept. 2010 to finish fourth in Serie A. Arsenal roared back to third place and another Champions League berth after a slow start to their 2011 Premier League campaign. Everton and Marseille both went from 20th to the top half of their leagues, while Paris Saint-Germain and AC Milan won their league titles going away after facing some early competition.
Washington Post: The keys to Juventus’ and Barcelona’s wins
For Juventus, the key was attacking a Real Madrid weakness. With superstar playmaker Luka Modric injured and defensive midfielder Asier Illaramendi out of favor, Madrid Manager Carlo Ancelotti shuffled his lineup. He played defender Sergio Ramos on the right of a midfield two, paired with Toni Kroos on the left. This pairing had been effective in the quarterfinal against Atletico Madrid, but Juventus seemed to have it sniffed out early.
Kroos was charged with driving forward from midfield while Ramos held the line in front of defense. On the flanks there was a similar pattern. Marcelo attacked from his left fullback position while Dani Carvajal remained mostly in reserve. The effect was a lopsided defense, and Juventus pounced on it from the start. Of Juve’s completed passes into the attacking third, about half were played down Madrid’s weaker left flank, compared to passes down the center of the pitch or on the right flank.
