We can't be optimistic about seeing Alvarez in the starting lineup, even after his move to ATM. It surprised me how ATM paid more than 80 million for him. That's pretty interesting to wait for his debut at ATM. Let's see how well Alvarez fits with Diego Simeone's strategy.
I think Alvarez won't be part of the starting lineup against Villareal, and he will start his debut from the bench.
The three teams will go to the opponent's house. I think the home supporters are able to make the players a little difficult. In addition, if you look at the results of last season, of course Madrid has the easiest opponent Mallorca, I am optimistic that Madrid can win. But for Atletico and Barcelona they will play against Villarreal and Valencia. These two teams were quite good last season. I think they are capable enough to make history of first defeats in the opening league games for Barcelona and Atletico Madrid. Maybe draw is also a good result for Atletico and Villareal.
