Per Mertesacker believes Manchester City will be triumphant in their Champions League quarter-final with Tottenham and go on to meet Barcelona in the final.
The reigning Premier League champions went down 1-0 to their domestic rivals in the first leg but welcome Mauricio Pochettino's men to the Etihad Stadium on Wednesday.
While former Arsenal and Germany defender Mertesacker is confident City can complete a comeback this week, he does not expect the same of their city rivals Manchester United, who trail Barcelona 1-0 ahead of Tuesday's game at Camp Nou.
