Mateta (knee) has avoided surgery and will look to return within the next two to four weeks, according to manager Oliver Glasner. "Fortunately, he doesn't need surgery [on his knee]. The injury is not as bad as feared, and so we think - and the opinion from several specialists and doctors - is that we can deal with the knee in a better way than with surgery. He will miss a certain time - I can't say two weeks, three weeks or four weeks - but he doesn't need surgery, that's very positive, so hopefully he's back soon. Of course, it's a disappointment, but now he's looking forward to the next months, and it's good for him that a final decision has been taken."
