Lautaro Martinez came off the bench to score all four goals for Inter Milan as they secured a 4-0 victory at Salernitana on Saturday that propelled them back to the top of Serie A.
The hosts had kept Inter at bay for the first hour but fell apart after Martinez came on nine minutes after the break and bagged four goals in 27 minutes, including one from the penalty spot.
The feat made history for Martinez, who became the first player to score four goals as a substitute in Serie A since the three-points-for-a-win era began in 1994.
Inter had dropped three points below AC Milan in the table after their rivals won 2-0 against Lazio earlier on Saturday, but returned to the summit with 18 points from seven matches. Salernitana are 19th with three points.
Bayern lose points
Bayern Munich struck twice in the second half to come from two goals down and snatch a 2-2 draw at RB Leipzig on Saturday but the champions dropped to third place in the Bundesliga with their second draw of the season.
Goals from Leroy Sane and Harry Kane in the second half cancelled out Leipzig's first-half lead but the result left Bayern on 14 points in third.
Kylian Mbappe was kept quiet and PSG could not find a way to score in a 0-0 draw at Clermont in the French league. Monaco took advantage of PSG's slip to go top after beating Marseille 3-2, with midfielder Maghnes Akliouche scoring twice and setting up the other goal.
