We must make sure we're at our best: Rooney

After their Premier League hot streak came to an abrupt end on Saturday, Manchester United aim to ensure there are no nasty surprises in Transylvania today.

Man United ace Wayne Rooney

United take on Romanian champions CFR Cluj in the Champions League smarting from their first home defeat to Tottenham for 23 years, yet knowing if they can return to England with maximum points, they will have one foot into the knock-out stages.

And that at least would be one objective for the season completed after last season's unexpected exit at the group phase. Wayne Rooney said: "If you are not at your best you get punished, which is what happened to us last season. We have to make sure that won't happen again this year so this is a big game for us."
