The sporting week in pictures, including Cristiano Ronaldo, Lionel Messi and Novak Djokovic

We pick out some of the key images of the last seven days taken from the likes of ATP Cup tennis, football's Spanish Super Cup and the Dakar Rally

It has been a big week for some of the biggest names in world football, with the likes of Cristiano Ronaldo, Zlatan Ibrahimovic and Lionel Messi all in action – with varying degrees of success.

In Italy, Ronaldo grabbed another hat-trick as Juventus swept aside Cagliari 4-0 in Serie A, while Swedish veteran Ibrahimovic was back in AC Milan colours, but his side could only manage a goalless draw with Sampdoria.

Meanwhile, in the revamped Spanish Super Cup being held for the first time in Saudi Arabia, Messi's Barca suffered a surprise 3-2 defeat against Atletico Madrid.

Double Formula One champion Fernando Alonso enjoyed a change in gear this week, as he took part in his first Dakar Rally.

After a solid start to the race in Saudi Arabia with co-driver and five-times Dakar winner Marc Coma, where he ended the first day 11th, the Spaniard was given a reality check on Stage 2 when he smashed his Toyota's suspension on a rock and lost two-and-a-half hours reparing a broken wheel. It resulted in them dropping down to 48th in the standings.
