The tiger will win every time it faces a lion

Tigers are more skilled hunters than lions.
Tigers can bring down large preys alone whereas, it takes several lionesses to do the same.
So, even in brute force tigers are ahead of lions. And if it is a male lion in the fight, the tiger will surely win for its experience in hunting as male lions are more like bullies than hunters.
Size and weight also matter in a fight and tigers win in both departments hands down.
So it is not much of a brainer to say that the tiger will be victorious every time he fights a lion.
