The most intriguing tie in the Round of 16 of the UEFA Champions League has lived up to its billing. Manchester United and Real Madrid were both excellent in their 1-1 draw at the Santiago Bernabeu, and there is no clear favorite for Tuesday's return leg at Old Trafford.

Danny Welbeck's surprising goal has United in a position to progress with a 0-0 draw, but this is possibly the least defensively adept Manchester United side that Alex Ferguson has managed. In previous years, with the likes of Park Ji-Sung and younger, healthier versions of Darren Fletcher and Nemanja Vidic, he may have played for a clean sheet in this situation. This year's Red Devils simply aren't built for that kind of game, and it's unlikely that Ferguson will attempt to play it.

Similar things can be said about Real Madrid and Mourinho, who has masterminded massive knockout competition victories by using defensive, counter-attacking tactics for a decade, with Chelsea, Inter Milan and Real Madrid. He's yet to break out that strategy in any edition of El Clasico or in Champions League this season, and he's probably not going to start with this match.

While there are a few lingering injury concerns for both sides, most of each teams' stars are 100 percent fit, and neither manager is missing any of their top attacking options. The biggest concern for either team is Phil Jones, the Manchester United utility man who was used to stifle Cristiano Ronaldo in the first leg of this tie.
