La Roja will be aiming to build on their 5-0 win against Slovakia while Croatia secured a spot in the knockout stages with a 3-1 win over Scotland
Spain face Croatia at the Parken Stadium in Copenhagen in an exciting last-16 encounter in Euro 2020 on Monday.
Despite the 5-0 thrashing of Slovakia in their final group game, question marks remain over Spain's ability to be clinical in the final third, with Luis Enrique's men scoring two or more goals in only four of their last 13 games.
Croatia, however, are not the strongest outfit defensively with only two clean sheets in the last 19 matches.
