Erling Haaland faces a race against time to be ready for Manchester City's clash against Liverpool next weekend after he was forced to pull out of Norway's game against Scotland.
The striker twisted his ankle after coming on in a 2-0 friendly win over the Faroe Islands on Thursday, although he carried on until the end.
It is his second ankle issue this month after he came off at half-time in the 6-1 demolition job of Bournemouth on November 4, raising concerns he may not be fit to play in the marquee fixture against the Reds.
