The 31-year-old Austrian has only made one League Cup appearance for the Hornets so far this season, having made 21 in the Premier League last term.
Watford have won all four of their opening matches in the league this season without Prodl in the lineup, and are currently third on the Premier League table. The defender has indicated that the lack of action hasn't bothered him yet, but he is worried it could make for a difficult time convincing Austria's manager he's worthy of inclusion when international fixtures come around.
Austrian source Laola1 also quote the player as saying:
“I’m no longer in the situation when I’m 24 years old and say I do not play for half a year or a year does not affect me greatly, I’m 31 now, I’ve seen a lot, I’ve gained routine and I’m still relatively relaxed I am not in a position to compensate for weeks, even months, but in the long run such a situation is personally unsustainable for the national team.
“I’m still not ready to pull the ripcord and change club, there will be injury and suspension, so if I’m the one who plays and we have such a run, things can change so quickly.”
