The draw for the first knock-out round of the Champions League takes place at the UEFA headquarters in Nyon, Switzerland, this afternoon.

Ten of the sides that advanced to this stage last season are still in the running, with Milan, Sevilla, Celtic, Schalke 04, Olympiakos and Fenerbahce the absentees.

The teams who were not in the last-16 draw last time around are Panathinaikos, Sporting Lisbon, Atletico Madrid, Villarreal, Bayern Munich and Juventus.

Eight of the 16 teams in the draw - those that won their sections in the group stage - are seeded. The unseeded clubs are the group runners-up.

Under the draw procedure, eight blue balls containing the names of the group runners-up are placed in a bowl. A first ball is drawn from the bowl containing the group runners-up. The team drawn is placed as the home team of match 1 as group runners-up play their first-leg match at home.

A bowl will be prepared with white balls containing the names of the group winners which are eligible to be drawn against the runners-up of match 1. A ball will be drawn from this bowl to complete the pairing of match 1.

This procedure is repeated for the remaining matches. If the computer indicates that only one group winner can be drawn, there will be no draw.

Further conditions: clubs from the same association must not be drawn against each other; the winners and runners-up of the same group must not be drawn against each other; the group winners must not be drawn against each other; the group runners-up must not be drawn against each other.

The draw for the first knock-out round and the pairings for the last 16 stage of the UEFA Cup will also be made today.

First KO round - to be played February 24/25 and March 10/11.
