The midfielder lamented two dropped points against lowly Las Palmas as he looked ahead to Sunday's visit from Diego Simeone's men
Sergio Busquets said Atletico Madrid will be a tougher battle as the Barcelona midfielder quickly turned his attention to the top-of-the-table clash following Thursday's shock draw at Las Palmas.
La Liga leaders Barca dropped points against relegation-threatened Las Palmas, who earned a 1-1 draw after Jonathan Calleri's penalty cancelled out Lionel Messi's 21st-minute opener.
Las Palmas were gifted the opportunity to equalise following the break when referee Antonio Mateu pointed to the spot, with Barca head coach Ernesto Valverde lamenting the "invisible penalty" post-match.
