Inter Milan's teenage striker Mario Balotelli has told skysports.com Manchester United could be made to pay for failing to find the net in Italy.
Sir Alex Ferguson's side secured a 0-0 draw in the first leg of their last-16 UEFA Champions League clash when the two sides met at Giuseppe Meazza.
The Red Devils were happy to keep Jose Mourinho's Serie A leaders at bay, but Balotelli believes that their failure to score an away goal could come back to haunt Sir Alex Ferguson's side.
The Italy Under-21 international, who is back in favour with Inter after falling out with Mourinho in January, sees United as slight favourites as they have home advantage.
But he believes if the Italian club's key men rise to the occasion then they will be able to halt United's bid for unprecedented trophy quintuple.
Balotelli told skysports.com: "In a European tie, 0-0 is not a bad score. If we score there, they will need to score two goals, which is not easy.
"It is now 55-45 for them because they are at home. They are a great team as we all found out in the first leg, however we are also very good.
"We will be ready for Old Trafford, our manager has got a great record there as well, so we will be fine, but it will be difficult.
"Hopefully our big players will do well and theirs will be off their game."
