Barcelona will use the mid-season break to regroup after losing their lead in the La Liga title.
The Blaugrana have won just one of their last seven league games and closed 2024 with a 2-1 loss at home to Atlético Madrid.
A first home defeat against Los Rojiblancos since 2006 changes the complexion of the title race as they will now lead the standings in early 2025.
Barcelona have struggled to translate their impressive UEFA Champions League form into domestic affairs and a response is needed in January.
Pedri opened the scoring that night, but Barcelona were unable to deal with the counter-attacking threat in the end, when Alexander Sorloth scored the winning goal in the 96th minute.
The Spain international became frustrated in the end and admitted his lack of ruthlessness in front of goal.
“It’s a tough defeat. We had opportunities to close the game and when you don’t close it, this is what happens,” Marca quotes.
“We had many clear chances. Robert, Raphinha, another one for me. Soccer is complicated if you don’t score goals.
“We need to be harder to beat at home. We have to improve a lot and take advantage of the break to recover mentally and physically.”
Barcelona faces a busy start to 2025, with a Copa del Rey trip to Barbastro on January 4, before immediately heading to Saudi Arabia for the Spanish Super Cup.
