Brazil defender Thiago Silva has praised Spain's strength in depth, saying that they will face a quality side in the Confederations Cup final.

The world and European champions progressed to the showpiece match after a 7-6 penalty shootout win over Italy in the semi-finals.

Having had a day less to rest, as well as having gone the distance against the Italians, Spain could make some changes for the final.

Silva, though, feels that the substitutes for Spain have just as much quality as the starters and admits that they will have to be well prepared to secure a third straight Confederations Cup title.

"We will face a team of great quality," the Paris Saint-Germain defender admitted. "They have a squad made up of reserves that are of the same level as the starters, a group that are world champions.

"We are well prepared to challenge Spain. I think that this game will be decided only by little details."
