The only reason Murray is included in this elite group is because he's from a western nation. Do you honestly believe if Andy Murray was from Russia or Iran he would be included in this top group by the western press?
1-5 in grand slam finals is terrible because it proves Murray has a block he just can't beat the elite players when it matters the most.
The only reason Murray is included is because the western media are desperate they want one their guys included when he doesn't deserve it. Murray needs to earn it and winning one slam isn't good enough to be a part of this elite group. To be a real champion a player needs to be a multiple slam champion someone that can rise and prove he is worthy. Murray's one slam only proves he had a hot moment that's it.
