Bayern Munich will be without Netherlands star Arjen Robben for Tuesday's Champions League quarter-final, first-leg, at home to Benfica on Tuesday with France forward Kingsley Coman set to return.

Both wingers missed Bayern's 1-0 home league win over Eintracht Frankfurt on Saturday at Munich's Allianz Arena to warm up for the visit of the Portuguese league leaders.

Coman, 19, sat out the win over Frankfurt with a slight leg knock, while Robben, 32, has been out with a groin injury since mid-March.

"I think Kingsley can play, but with Arjen one must continue to be a little more patient," said Bayern's chairman Karl-Heinz Rummenigge ahead of the Benfica match.

Meanwhile, Rummenigge has said Bayern's Germany centre-back Jerome Boateng may be back on the pitch sooner than expected after tearing his groin in January.

The 27-year-old trained with the ball for the first time on Friday and had set himself the goal of mid-April for his return, but could be back for the German league leaders sooner.

"It looks quite good for Jerome, he has started training again and maybe he will come back a bit earlier than expected," added Rummenigge.
