Giovanni Trapattoni is confident his Republic of Ireland players will not allow their anger to boil over as they attempt to dump France out of the World Cup.
There were a series of furious confrontations on the pitch at Croke Park on Saturday night after the Republic’s 1-0 defeat in the first leg of their play-off.
The bust-ups were sparked by Lassana Diarra's comments to Keith Andrews — which he has since denied making — suggesting that the Republic's dream was at an end.
However, while the Real Madrid midfielder may have provided the Irish with a little extra motivation, Trapattoni has no fears that his players will lose their heads at the Stade de France tonight.
He said: “I have said to the players, these games are for warm hearts and cool heads. We must play with cool heads, but warm hearts.
“With feet, we can score goals. If we keep cool heads, we can use our feet to score goals.”
