The Frenchman has taken aim at the coaches of Real Madrid and Paris Saint-Germain for defensive substitutions that have cost their teams over the past few days.Raymond Domenech has taken to Twitter to criticise Jose Mourinho and Carlo Ancelotti over perceived negative tactics.Real Madrid boss Mourinho saw his side slump to a 2-1 defeat at Bayern Munich in Tuesday\'s Champions League semi-final first leg, while Ancelotti\'s PSG were held to a 1-1 draw at bottom side Auxerre in Ligue 1 at the weekend.Both coaches have received criticism for handing the opposition the initiative by making defensive substitutions during the latter stages of their respective matches.And former France boss Domenech is the latest to question what he sees as the flawed logic of making negative changes to protect a result.\"They are only upset at the truth: defensive changes are not suited to safeguard a result. Same causes, same effects. Mourinho, Ancelotti,\" Domenech tweeted. Madrid must win next week\'s return leg at the Santiago Bernabeu to progress to the Champions League final, while PSG are two points behind Montpellier in the Ligue 1 standings with six matches left.
