Republic of Ireland manager Giovanni Trapattoni has admitted that he may rethink his tactics after he watched his side draw 0-0 with Hungary.
The Italian had previously named the team he was going to pick for the Euro 2012 opener against Croatia, but appears to have now had a change of heart after watching the goalless draw.
Hungary enjoyed large spells of domination during the game, and Trapattoni feels that it is his duty to consider other strategies.
"I have to show the team what happened this evening because it is my duty and we need to change," said Trapattoni. "We must understand why. I know why, I knew before why, yesterday and the day before.
"When we meet a team with one striker, I know that between two lines, we are in difficulty. To have a balance, we have to give up one striker or put one more in midfield.
"In the past, I know this position, I know this lineup. I will speak with the team and I will show them our difficulty because we need to take a decision to sacrifice a striker, or we need to change the situation."
Ireland and Croatia are joined in Group C by Spain and Italy.
