Arjen Robben will miss up to six weeks with a muscular injury. Tests carried out on Sunday morning have confirmed an adductor muscle injury.

Robben was restricted to 15 Bundesliga appearances last season due to a similar injury.

Robben is now likely to miss Bayern’s German Supercup fixture with Borussia Dortmund, their opening DFB-Pokal game at Jena and first Bundesliga match of the season against Werder Bremen on 26 August.

Cristiano Ronaldo has visited a clinic while on holiday in Ibiza for hyperbaric oxygen therapy to speed recovery from his current knee injury, according to a report in Marca.

Ronaldo picked up the injury from a Dimitri Payet challenge in the Euro 2016 final.

Ronaldo has reportedly twice visited the Clinica Evidental -- a dental clinic which according to Marca also provides the hyperbaric oxygen therapy treatment as an additional service.

Ronaldo has suffered from a series of knee problems in the past, with a tendonitis problem during the 2013-14 club campaign and 2014 World Cup putting his career at risk, although more recently that issue appeared to have eased.

Cristiano Ronaldo had to come off the Euro 2016 final after just 25 minutes due to a knee injury.

Ronaldo was injured in a collision with Dimitri Payet in the ninth minute.

Ronaldo needed treatment multiple times and tried to continue but was unable to run.

Fernando Santos said at his prematch news conference that he does not believe Ronaldo will retire from international football after the game.
