Simy Nwankwo finally got his breakthrough at Salernitana with his first goal for the club while Chidera Ejuke and Victor Osimhen scored crucial goals that powered their teams to victory.
Ejuke scored the only goal in Sunday's Premier League game as CSKA Moscow edged Ural 1-0.
It was the Nigeria winger's second league goal of the season after 10 appearances.
Osimhen continues to bang in the goals for Napoli and he was their saviour against Torino in a Serie A match on Sunday.
The teams were tied for the majority of the encounter until the 22-year-old powered a header into the back of the net in the 81st minute, which extended his team's unblemished start to the season.
Napoli are yet to drop points in the Italian top-flight and they are at the top of the table with 24 points after eight games.
Awoniyi scored his sixth Bundesliga goal of the season in Union Berlin's 2-0 triumph over Wolfsburg on Saturday.
The former Liverpool striker broke the deadlock for the hosts in 49th minute and he was later replaced in the 84th minute.
The lanky striker ended his seven-game goal drought in the Serie A with his maiden effort for Salernitana on Sunday.
Simy scored his side's only goal in the 39th minute following an assist from compatriot Joel Obi.
However, Salernitana could not preserve the lead as they conceded two goals in the second half which drew them back to the bottom of the table.
The Nigeria international made another impression on his second Premier League start of the season which helped Leicester City secure a 4-2 comeback win over Manchester United.
Iheanacho joined Vardy in leading the Foxes' attack on Saturday and shortly after they found themselves behind, he played a role in turning the game around.
He provided the assist for Youri Tielemans in the 31st minute to cancel out Mason Greenwood's opener, which inspired them to victory.
