Madrid perfect in Portugal, N'Zonzi the pass master - Champions League in Opta numbers

Real Madrid will hope to continue their impressive goalscoring run against Portuguese opponents away to Sporting CP on Tuesday as they look to secure Champions League progression.

In their last 20 meetings with Primeira Liga sides, Madrid have never failed to find the back of the net, encouraging news ahead of a trip to Lisbon in Group F – where a point would confirm a last-16 berth for Zinedine Zidane's holders.

Borussia Dortmund's clash with Legia Warsaw also promises goals if the teams' form so far in this season's competition is anything to go by, with the latter hoping to avoid breaking an unwanted record.

In Moscow, meanwhile, CSKA goalkeeper Igor Akinfeev continues his long wait for a clean sheet against Bayer Leverkusen.

With the help of Opta, we bring you the best stats for Tuesday's Champions League group stage fixtures.
