Manchester United striker Wayne Rooney says Tuesday's 0-0 draw in the first-leg of their Champions League tie at Inter Milan is "dangerous".
"We had enough chances to give ourselves the best chance of going through," reflected Rooney.
"It is a dangerous scoreline. If they get one goal it is going to be difficult for us.
"I have seen a few of Inter's games and it seems to me like Inter are probably better away from home. They can just sit there and defend, then try to hit you on the break.
"But it is also a good result because our own home form is excellent, so if we defend well and take our chances we will be OK."
