Mourinho managed to send Manchester United crashing out of the Champions League in 2004 while at Porto.
“They kept us hanging on at the end being last out of the hat, but it’ll be interesting to come up against Jose again,” Ferguson told MUTV. “He’s a character with a good personality and I’ve always got on well with him.
“He knocked us out of the competition when he was at Porto, so I hope we have the luck they had in that tie this time round.
“We’ve played against most of their players over the years and faced them in a friendly last year at Old Trafford. So we know all about them. Hopefully we can do the job there in the first game and give ourselves a platform to take back to Old Trafford.
“Playing against the bigger teams brings a better focus and concentration to our game as we showed against Barcelona last season. We knew the most important thing we had to do in that tie was to concentrate and our concentration in both games was terrific.”
