Mendoza hoped the Duke of Guise would rule France.

Evidence

Mendoza had already discounted, too, the Anglo-French alliance. The only power in France he even half-way trusted was that of the Holy League and its chieftain, the Duke of Guise. When the moment of the Enterprise came, not Henry of Valois, Mendoza hoped, but Henry of Guise would be master of France. — Garrett Mattingly, The Defeat of the Spanish Armada, 95
