Andy Murray says he faces a "formidable" challenge to win Wimbledon for a second time despite Novak Djokovic's surprise exit.
Murray, the 2013 champion, faces Australia's Nick Kyrgios in the fourth round on Monday.
"There are some pretty decent players left in my way, so I'm not getting carried away," Murray wrote in his BBC Sport column.
Day seven also features Roger Federer and Serena Williams.
'I have the weapons to beat Murray'
Kyrgios has yet to beat Murray in any of their previous four meetings.
