I would say we feel pretty confident about eliminating Tirana. We are way way better at home this season (compared to on the road), and look to continue our fantastic home-streak counting the last 6 games. Obviuosly, the players have to give it 100% as Tirana is a decent team. Personally I predict 2-0 or 3-0.
As far as team news is concerned, no new injuries. We will definitely play with two strikers this time (4-4-2).
Injuries happen at about the same rate as on normal grass I guess. No research, as far as I know, have shown that artificial grass is worse when it comes to injuries.
