Title holders AC Milan take on Arsenal in the second-leg of the UEFA Champion League round of 16 at the San Siro on Tuesday. Milan welcome back a playmaker Kaka who has struggled to be fit for Tuesday's clash. "Recently we have paid for the absence of quality players, but we have recovered them all for tomorrow, Kaka included, and I'm sure we will produce a great performance," coach Carlo Ancelotti told a news conference. Ancelotti also has Alessandro Nesta and Andrea Pirlo back from injury; but will be missing Clarence Seedorf, Emerson and Marek Jankulovski. Arsenal manager Arsene Wenger has also Tomas Rosicky and Kolo Toure out of Tuesday's clash while Robin Van Persie has recovered from a thigh injury that has sidelined him since January. With the first-leg ending in a goalless draw, any goal for the Gunners will mean that the hosts have to respond with at least two. Manchester United v Lyon United are fortunate to have scored a late goal in the first-leg, courtesy of Carlos Tevez, to end cancel out Karim Benzema's opener and end the game in a 1-1 draw. "Tevez is proving a master at scoring the really important goals - the ones that give you a win or a draw, especially away from home," United's coach Alex Ferguson said. "He did it at Tottenham (Hotspur) to salvage a point as he made the result 1-1. He scored for a 1-0 win at Liverpool and now he has rescued us again by finding the net late and nullifying Lyon's lead." Even though the Scotsman declared that Tevez's goal put Manchester United in "a good position", the Argentine international is not guaranteed a starting place. Wayne Rooney is expected to lead the Red Devil's attack with Cristiano Ronaldo and Ryan Giggs playing supporting roles. Ferguson's biggest scare will be Benzema.
Ronaldo "He is a very strong boy, he reminds me of Zidane physique-wise and possibly pace-wise too. He is a natural centre-forward, I think." Barcelona v Celtic Former European champions Barca are expected to shake off their lackluster performance in the 4-2 defeat against Atletico Madrid on Saturday and annihilate Celtic at Nou Camp. Celtic manager Gordon Strachan admitted that his team has a mountain to climb especially with the first-leg ending in a 3-2 defeat. "It's a big climb and quite a few people have died trying to climb it," said a metaphorical Strachan. "It's difficult but we've put ourselves in this position because of the way we played in the first leg. Barcelona played very well then and I'm looking for an improvement from my players," he added. While Barcelona remain favorites to go through, captain Carles Puyol remains worried about the form of his team's defense. "We conceded a lot of goals and we have to work on our defense and recover our defensive solidity." Coach Frank Rijkaard also highlighted the importance of taking charge of the game. "We will have to play well if we are to finish the job. We can't afford to relax. We'll have to work very hard to get through to the next round," he said. Sevilla v Fenerbahce One goal will be sufficient for the hosts to make their first appearance in the Champions League quarter-finals. The first-leg in Turkey ended in a 3-2 win for Fenerbahce.
