It is maybe time to retire for Osmany .
I wouldn't go as far as retiring yet but my opinion is I don't believe Lube can compete with Perugia or even Modena in the final once they take the semifinal from Trento now that he have knee problems.
I probably would just focus and heal for the champions league.
I think Kovar is good enough now that Leal is stabilizing. Ofcourse it is a gamble against Trento but if his condition worsens then this season is basically over for Lube.
