This season's Champions League is in full flow as we reach the halfway point of the group stages. The reigning champions, Bayern Munich, have started the defence of their fifth European Cup in style, winning all three of their matches while conceding just one goal.
Another impressive side so far is Diego Simeone's Atletico Madrid, who have also won all three of their opening matches.
Some teams, like Viktoria Plzen and Real Sociedad, are struggling as they sit bottom of their group without a win.
Players performing to their usually high standards are Cristiano Ronaldo, Zlatan Ibrahimovic and Lionel Messi. Franck Ribery, Robert Lewandowski and Sergio Aguero have also impressed.
