Mainz 0-1 Leverkusen
Goal: 0-1 Alario (30')

Ahead of Thursday's UEFA Europa League start against Nice, Leverkusen coach Peter Bosz might have been tempted to look ahead. But with his side winless in their opening three league games, his focus was on improving that record, especially against a Mainz side yet to pick up a point this season. The Dutchman named a strong starting XI that included — for the first time this season — Leon Bailey. The Jamaica international nearly rewarded his boss' faith with an early goal, but his instant lobbed return to Robin Zentner's poor punch sailed just wide of the empty net. Jeremiah St. Juste's brave block means we'll never know just how sorely Daley Sinkgraven's fierce volley would have tested Zentner. The German goalkeeper found Alario's close-range header too hot to handle, and though he clawed the ball back, it had already crossed the line to give the Argentine forward his first Bundesliga goal — and corner-kick taker Bailey his first assist — of the season.

Nadiem Amiri shot straight at Zentner from an Alario knockdown early in the second half as Leverkusen sought to make life more comfortable for themselves, and Alario headed straight at the Mainz keeper with the visitors dominant. They might have lost their grip on the game had Edmond Tapsoba's red card 12 minutes from time stood, but the Burkina Faso international avoided an early bath as the man he had brought down, Karim Onisiwo, had strayed offside before bursting through on goal.
