It promises to be another week of busy action for Chelsea's internationals, with players at all levels on duty for their countries either in Europe or Africa.
Petr Cech will be hoping for two clean sheets at home when his Czech Republic side host Malta on Friday and Bulgaria on Tuesday. The first game takes place in Cech's home town of Plzen, the second in Prague.
Branislav Ivanovic will be expecting a tough time when Belgium visit Serbia in Belgrade on Friday, the defender, who captains his country, could well be marking one Eden Hazard. The Belgian squad also contains the on-loan Kevin De Bruyne and Thibaut Courtois, and they entertain Scotland in Brussels next Tuesday after the Serbian test. Serbia travel to Macedonia.
The English contingent of Gary Cahill, Ashley Cole, Frank Lampard and Ryan Bertrand, the latter being added to the squad on Monday, have two qualifiers, at home to San Marino on Friday, and away to Poland on Tuesday. If selected for both games, Cole will reach the 100-cap mark, while Lampard, if fit, could captain the side on Friday with Steven Gerrard suspended.
In Africa, there is an important Cup of Nations qualifier for John Mikel Obi and Victor Moses of Nigeria. They meet Liberia in Calabar on Saturday, needing a win after drawing the first leg away from home last month, 2-2.
World champions Spain do not need to qualify for Brazil 2014, and so have two friendlies to occupy them. Fernando Torres is the only Chelsea man involved as they travel to Belarus on Friday and host France in Madrid on Tuesday.
As well as the Spanish, the hosts also qualify automatically, and Brazil's recent roadshow continues with games against Iraq in Sweden on Thursday and Japan in Poland on Tuesday. David Luiz, Ramires and Oscar are all in contention.
