The Germany international made his return from a thigh injury in a friendly last weekend and could make his competitive debut for Pep Guardiola's side against Eintracht Frankfurt
The former Borussia Dortmund playmaker missed the Bavarians' pre-season campaign with a thigh injury which ruled him out of last season's Champions League final, but he made his first appearance for die Roten last weekend, scoring twice in a 30-minute cameo in a friendly against Gyori.
Consequently, Guardiola has decided to call upon Bayern's big-money signing for the trip to the Commerzbank Arena.
"He made another step this week, and is getting better step by step," the Catalan coach told reporters on Friday. "He'll come to Frankfurt with us.
"He will be in the squad but I will not decide the line-up until the last moment."
Bayern opened the defence of their Bundesliga title with a 3-1 win over Borussia Monchengladbach last weekend, but Guardiola felt his side had been nowhere near their best.
"We played a good pre-season and I hope we can keep up to that level," the ex-Barcelona coach explained. "Right now, we couldn't win the championship, but we will improve."
