Madrid: Xavi was a surprise omission on Thursday from Spain coach Vicente del Bosque`s squad for the world champions` Euro 2012 Group I qualifiers against Lithuania and Scotland next month.
The Barcelona playmaker, whom a Spanish soccer federation (RFEF) spokeswoman said was suffering from an Achilles problem and had asked to be rested, joins fellow midfielder Cesc Fabregas and defender Raul Albiol on the injury list.
Fabregas damaged a hamstring during Arsenal`s 1-1 draw with Sunderland on Sept. 18 and was expected to be out for two to three weeks.
"We have two fundamental matches which are extremely dangerous," Del Bosque, who will lead Spain against Lithuania in his native Salamanca on Oct. 8 and against Scotland in Glasgow on Oct. 12, said at a news conference.
"Lithuania are a well-organised side who don`t allow you space, with competitive players," he added.
"Scotland, playing at home, will be tough. We cannot afford the slightest stumble. We are preparing ourselves for a difficult test."
Spain, winners at Euro 2008, began their title defence with a 4-0 win in Liechtenstein earlier this month.
