Welcome to text coverage of Roger Federer's Australian Open quarter-final against Jo-Wilfried Tsonga.

TSONGA 1-2 FEDERER - Tsonga finds that big serve to gain control of this game. He then out-lasts his rival in a rally for 40-0 before a little jump on the backhand sees him hitting long. Federer sends back a body serve to close the gap to 40-30, but a long return sees Tsonga get on the board in this match.

TSONGA 0-2 FEDERER - Straightforward service game to love from Federer. He opens it with one of those stylish dipping winners to the corner, and his serve does the damage from there.

TSONGA 0-1 FEDERER - BREAK - Long from Tsonga on the first point but he responds with a soft volley to level at 15-15. An early double then smash gives the Swiss two break points, and he seals the break with the second of them. /// @SerPeker: "federer in 3 straight sets symco. hi from turkey bro"

Off we go then. Tsonga to serve in the first game.

However they played one another a ridiculous eight times in 2011, with Federer winning six of them. Most were on hardcourts, with Tsonga winning one of those and also on the grass of Wimbledon - remember that quarter-final comeback?

The head-to-head is 8-3 in favour of Federer. They did not meet last year, with Federer pulling out of their Doha last-four meeting with a back injury.

The players making their way out on to the court. Can Tsonga's power game be a match for the sublime tennis of Federer?

The Swiss Maestro has won four Aussie Open titles and lost in one final. Tsonga got to the final in 2008 and semis in 2010.

Tsonga was too good for French compatriot Richard Gasquet in the fourth round, while Federer eased past Milos Raonic.
