Celtic are chasing a win at already qualified AC Milan [ Images ] later on Tuesday even though they just need a draw to reach the Champions League [ Images ] last 16.

The Scottish champions beat the holders 2-1 at home in October, when Milan keeper Dida feigned injury, and coach Gordon Strachan has said they will not change their attacking ways at San Siro, where a win would put Celtic top of the group.

A defeat for Celtic though, against a probable Milan reserve side would give Shakhtar Donetsk the chance to reach the knockout stages for the first time, if they can overcome eliminated Benfica [ Images ] at home.

Benfica still have the opportunity of reaching the UEFA [ Images ] Cup last 32 as a victory in Ukraine would lift them over Shakhtar into third.

The last round of matches in Group D has been brought forward by a week because European champions Milan jet off to the Club World Cup in Japan [ Images ] following Tuesday's games.
