Fed fell last night in whats looking like beginning of his swansong , but all the top 3 seeds are still in it with chance for Murray to retain his title and possibly face Nadal who will almost certainly make the final.
In Murrays way stands Djoker in semis ( assuming both make it ) meaning the winner will prob have a tough task ahead of him ( given their typical matches are 5 sets )
Djokers done it before but Murray has never beaten 2 of the top 3 ( what used to be 4 with Fed ) back 2 back to win a GS. nor Nadal at a GS , and he will have to both in theory if he wants to have a chance.
Can he do it ?
Well, its big ask , but if he can you could argue this would be his most impressive win of all - esp if he can beat his proverbial bogeyman in Nadal ( Nadals leads 13 -5 in overall H2H )
