CHELSEA INTERNATIONAL CALL UP ROUND UP

It is going to be a busy and decisive time for many of Chelsea's internationals over the coming week, with places at next summer's European Championships up for grabs.

Already qualified are the Spanish pair of Fernando Torres and Juan Mata, but they can still have a big say on which side will progress to the play-offs. On Friday they travel to Prague to face Petr Cech and Czech Republic, before hosting Scotland in Alicante on Tuesday.

The Czechs currently occupy second spot, two points ahead of the Scots in Group I, and travel to Lithuania after meeting Spain, while Scotland's other game is away in Liechtenstein.

The English trio of John Terry, Frank Lampard and Ashley Cole will qualify for Poland and Ukraine if they avoid defeat in Montenegro on Friday night. Defeat would lead them sweating on how the Montenegrins then do against Switzerland on Tuesday.

Portugal and Raul Meireles sit atop Group H with two games remaining, but they are level on points with both Denmark and Norway. They entertain Iceland in Porto on Friday, before travelling to Copenhagen to meet the Danes on Tuesday. Maximum points will guarantee qualification.

It is a similar situation for Florent Malouda's France, who are clear by a point at the top of Group D. By beating Albania and avoiding defeat against second-placed Bosnia and Herzegovina in their final game, both matches at home, they would guarantee qualification. Those games are also on Friday and Tuesday.

Both Romelu Lukaku and Branislav Ivanovic are playing for second place in their respective groups, the Belgians having already lost out to Germany, and the Serbians to Italy.

Lukaku is in the squad for Belgium that hosts Kazakhstan in Brussels on Friday before travelling to Dusseldorf to face the Germans on Tuesday. If they win both they should qualify for the play-offs above Turkey, who meet Germany and Azerbaijan. He is joined in the group by our on-loan goalkeeper Thibaut Courtois.

Serbia are at home to Italy on Friday and away to Slovenia on Tuesday. Three points from those two games would be enough for a November play-off spot.

Yossi Benayoun, on loan with Arsenal, cannot qualify with Israel, as they trail group leaders Croatia and Greece by too far. They meet Malta in the final group game on Tuesday.

In Africa, John Mikel Obi's Nigeria need to win by two clear goals against Guinea on Saturday to guarantee qualification for the African Cup of Nations in Gabon and Equatorial Guinea. They then meet Ghana in a friendly on Tuesday. Both games take place in Abuja.

Didier Drogba and Salomon Kalou are already qualified with Ivory Coast and entertain Burundi in their final group game on Sunday.

Finally there are two friendly matches for Brazil's David Luiz. He is in the squad that travels to play Costa Rica on Friday, and Mexico on Sunday.

There is plenty of action at Under 21 level also, with five promising talents called up for national service.

Oriol Romeu's Spain play away to Croatia on Thursday, while Josh McEachranis in the England group that plays away games in Iceland and Norway.

Conor Clifford's Republic of Ireland travel to Liechtenstein on Tuesday, while loanees Patrick van Aanholt (Holland) and Milan Lalkovic (Slovakia) play away in Austria and Latvia on Thursday and Monday respectively. They are all European qualifiers.

At Under 19, England have three youngsters in the squad that meets France, Portugal and Ukraine in a mini-tournament for European qualifying in France, with those games taking place on Wednesday, Friday and Sunday. They areJamal Blackman, Nathaniel Chalobah and Todd Kane.

Philippp Prosenik will be representing Austria on home soil in a similar format, with games against Malta, Albania and Denmark.
