Geneva, Dec 16 (IANS): In a repeat of last season's Champions League round of 16 clash, won by Barcelona, the La Liga giants will take on England's Manchester City again, in a "very difficult tie", according to Barcelona coach Luis Enrique.

Barcelona got the better of City in last season's Champions League round of 16, winning 2-0 in Manchester and 2-1 at the Camp Nou, reports Xinhua.

"They are a very difficult team, among the toughest two teams in the draw, the team everyone wanted to avoid and a team that are one of the contenders to win the Champions League. We will have to analyse City very closely, but we also have to remember that this tie will take place in February and many things can happen between now and then, teams can change a lot," said Enrique.

"When the moment arrives, we will analyse them. We are certain that the tie will be very close because they are one of the contenders for the trophy and they have strengthened their team by signing some interesting players.
