Which is the most difficult fielding position for a fielder in Cricket?

forward short leg for sure, I fielded there only once but vowed never to put myself in that position ever again. India's Yajuvender Singh once held 7 catches in that position & in the 70s, when India's quartet of spinners was famous and doing well, guy called Eknath Solkar, was positioned there and pulled off many majestic catches, he is dead but still I'd put his name for the same position, even today, he was a legend.
