Inter Milan kept up the pressure on Serie A leaders Napoli on Sunday with a convincing 4-0 win at lowly Lecce which moved the defending champions three points from the summit. Goals from Davide Frattesi, Lautaro Martinez, Denzel Dumfries and Mehdi Taremi gave Inter their seventh win in eight league matches in a dominant performance in southern Italy. Simone Inzaghi's team are also four points ahead of third-placed Atalanta with a game in hand on both their title rivals, their match at Fiorentina which was stopped in December due to Edoardo Bove's on-pitch collapse.
