Gray scores on debut in Leverkusen win
Both Wolfsburg and Bayer Leverkusen remained hot on RB Leipzig's heels with wins on Sunday (AEDT) in the Bundesliga.
Second-half goals from Wout Weghorst and Ridle Baku gave Wolfsburg its fifth win in a row, a 2-0 result away to Augsburg, while Leverkusen was a 5-2 home winner in an entertaining clash against Stuttgart.
Kerem Demirbay put Leverkusen in front with a neat back-heel volley from close range on 18 minutes and nutmegged Stuttgart goalkeeper Gregor Kobelbund to double the lead shortly afterwards.
Sasa Kalajdzic struck twice in the second-half, but his second was a mere consolation goal. Leon Bailey and Florian Wirtz had already given Leverkusen a commanding lead.
English winger Demarai Gray, who joined Leverkusen from Leicester City in January, added a fifth before full-time on his debut to pick up his first Bundesliga goal.
Elsewhere, second-from-bottom Mainz moved to within four points of safety as Moussa Niakhate's first-half penalty gave it a hard-fought 1-0 win at home to Union Berlin.
