Paco AlcÃ¡cer was Barcelonaâs match-winner, his double helping the La Liga leaders to a 2-1 home success over Sevilla for their 10th victory in 11 games.
The recalled AlcÃ¡cer, who endured a disappointing first season at the Camp Nou, was making only his second league start of the campaign. He made an impact by putting the hosts ahead midway through the first half.
And after Guido Pizarro had levelled for Sevilla after the break with a header from a corner, another first-time finish from AlcÃ¡cer restored Barcaâs lead, and their four-point advantage over Valencia at the top of the table.
In Serie A, GastÃ³n RamÃrez and Fabio Quagliarella fired Sampdoria to a 2-0 win at Genoa in the Derby della Lanterna. The former Southampton and Middlesbrough forward RamÃrez and the Sampdoria captain Quagliarella pounced either side of half-time.
The Colombia forward DuvÃ¡n Zapata laid on both goals for Marco Giampaoloâs team, who secured their fourth win in five Serie A matches to stay sixth in the table.
Genoa slumped to their third straight defeat and fourth game without a win, to remain third bottom.
Crotone inflicted a fourth loss in a row on Bologna, the visitors edging home 3-2. Ante Budimir struck twice, with Marcello Trotta scoring a penalty. Simone Verdi scored twice for the hosts, but that proved in vain, as Crotone secured their first win in five matches.
In Ligue 1, Edinson Cavani moved past 100 goals in the French top flight as Paris St Germain thrashed Angers 5-0.
Cavani and Kylian MbappÃ© both struck twice, with Julian Draxler also on target for Unai Emeryâs unbeaten side, who won their 10th match in 12 at little more than a canter.
PSG hardly even missed Neymar, who sat out the clash with a thigh problem. The Brazil full-back Dani Alves was the true star of the show, laying on two eye-catching assists in a vintage performance to belie his 34 years.
Not to be outdone, second-placed Monaco thumped Guingamp 6-0 at home. Guido Carrillo and Adama TraorÃ© both found the net twice, with Keita BaldÃ© and a Fabinho penalty completing the rout.
Despite Monacoâs riposte however, PSG remain four points clear at the top of the table.
Adrien Thomasson and Emiliano Sala ensured Nantes edged out Toulouse 2-1. The visitors were level on the hour thanks to an Alexis Blin goal, but Sala hit back for Nantes seven minutes later in what proved the decisive blow.
