Ibrahimovic, Ronaldo, Messi - who will be Champions League top scorer this season?

The Sweden international currently leads the goalscoring charts, but he faces stiff competition from the Spain-based duo

With the Champions League slowly approaching its business end, the race for the top scorer title is hotting up.
Real Madrid star Cristiano Ronaldo sat top of the goalscoring charts following the group stage with nine strikes, but last week Zlatan Ibrahimovic leapfrogged him with a double in Paris Saint-Germain's 4-0 win over Bayer Leverkusen.
Ronaldo and Madrid are yet to play the first leg of the last 16, though, so the Portuguese has the chance to add to his tally in Wednesday's away game against Schalke.
Elsewhere, Lionel Messi has not given up on the Champions League Golden Boot. The Argentine currently sits on seven goals, with Barcelona all but through to the quarter-finals at the expense of Manchester City.
The Premier League giants have two candidates for the top scorer title in the form of Sergio Aguero and Alvaro Negredo, but both will have to be at their best in the second leg at Barca if they are to overturn a 2-0 deficit and threaten Ibrahimovic.
Another striker who will still be dreaming of challenging for top spot is Atletico Madrid's Diego Costa, who has now netted five times following his winner against AC Milan last week.
Additionally, outsiders such as Robert Lewandowski (Borussia Dortmund), Edinson Cavani (PSG) and Thomas Muller (Bayern Munich) are all still in contention, but will have to find their scoring touch in the next few games if they are to have a realistic shot at the Champions League Golden Boot.
