So, about Alvaro Morata's Atletico Madrid debut.
The La Liga outfit snapped up the out-of-form Spanish striker on an 18-month loan deal from Chelsea, and he made his debut for the club on Sunday but it didn't go to plan.
He played the full-90 minutes as Atletico Madrid slumped to their first defeat in 19 games thus failing to capitalise on Barcelona dropping points at home to Valencia.
Sergio Canales' bagged the only goal of the game, converting a second-half penalty to secure all three points condemning Atletico Madrid to their second league defeat of the season.
Barcelona remain at the top of the league with 60 points on the board, six points clear of Diego Simeone's men.
By offloading Morata, Chelsea snapped up Gonzalo Higuain and he got off the mark in stunning fashion over the weekend.
He bagged a superb brace including a 25-yard beauty in Chelsea's 5-0 Premier League victory against Huddersfield Town.
