Roger Federer returns to London one last time: 'It's been a great, great journey. For that, I'm really grateful'

Roger Federer is back in London, the home of perhaps the greatest achievements in a career packed to the brim with glorious moments. For there has been Wimbledon, where the Swiss star won the junior title in 1998, then beat his idol, seven-time champion Pete Sampras, in 2001. Federer was still just 19 years old, but it would be their only meeting, as Sampras retired the following year.
