Liverpool midfielder Thiago has not been included in the Spain squad for their upcoming Nations League games against Switzerland and Portugal.
The 31-year-old has made just three appearances so far this season (excluding the Community Shield), including just one Premier League game. He picked up a hamstring problem on the opening day against Fulham and missed the Reds' following five games.
Thiago returned to action at the start of the month and played just under half an hour of the 4-1 defeat away at Napoli last week. He made his first start since the Fulham draw midweek in the 2-1 win over Ajax in the Champions League.
