Former Poland keeper Jerzy Dudek fears that a series of injury worries ahead of his nation's Euro 2016 battles with Scotland and Ireland next month is enough to give the Polish coach some more grey hairs.
While recent injury concern Robert Lewandowski eased fears about his fitness by coming off the bench to score a stunning five goals in nine minutes for Bayern Munich in a league game against Wolfsburg last night, the fitness of some key players is a concern to ex-Liverpool man Dudek.
Séamus Coleman was not in the Everton squad for their League Cup tie last night but should he, as expected, return from injury in time for international duty, Martin O'Neill will have almost a full-strength squad, with Kevin Doyle the only absentee due to injury.
"The situation with a few players is a worry," says Dudek. "Jakub Blaszczykowski is injured again and he has only played one full game for Fiorentina.
"Robert Lewandowski has had an injury and Lukasz Piszczek is not playing for Borussia Dortmund at the moment. Then you have the situation with Wojciech Szczesny's finger," he added, referring to the injury which Szczesny picked up in a clash with Luis Suarez in the Roma-Barcelona Champions League tie last week.
"At least we have some back-up in goal. Lukasz Fabianski is the No. 1 keeper at the moment, and he is showing his reliability in the Premier League. In goal we have three or four options, should something happen to Fabianski, but you can't say the same about other positions in the team, especially defence" said Dudek.
"I think Adam Nawalka will get some more grey hairs in the next few days and he can only hope that the injury list doesn't get any longer."
Lewandowski had sat out Bayern Munich's league win over Darmstadt but reappeared in last night's Bundesliga clash with Wolfsburg. Blaszczykowski wasn't even in the Fiorentina squad for their weekend league game but could feature in a Serie A game tonight.
Home-based defenders Michal Pazdan and Tomasz Jodlowiec are also injury concerns.
