The Bayern Munich defender is confident the pair can be replaced if they cannot prove their fitness ahead of the World Cup in Russia
Manuel Neuer and Jerome Boateng face a race against time to prove their fitness for Germany's World Cup campaign, but Mats Hummels feels the reigning champions will be able to replace the key duo.
Bayern Munich captain Neuer has been out of action since September due to a broken foot, while his club colleague Boateng suffered a hamstring injury in the first leg of the Champions League semi-finals against Real Madrid in April.
