Arsenal manager Arsene Wenger has revealed Sol Campbell will play from the start in tomorrow night's Champions League semi-final second leg against Villarreal.
The England defender is included as a result of a knee injury sustained by Philippe Senderos which Wenger fears will keep the Swiss player out for three weeks.
Wenger said: 'Senderos is out, so Sol will start the game. It is a little gamble because he has not had the number of games you would wish him to have, but physically he looks all right.'
Wenger expects the results of medical scans to show ligament damage which will keep Senderos out for around three weeks.
Campbell has started just one match since being substituted at half-time against West Ham on February 1, following a performance which left many questioning his form ahead of the World Cup.
He is available again after recovering from an operation on a broken nose and will be expected to slot in as a direct replacement for Senderos alongside Kolo Toure in central defence.
Senderos suffered his injury in the 1-1 draw with Tottenham on Saturday.
Left-back Gael Clichy is also included in the travelling party, available again after suffering a stress fracture of his foot while on Under-21 duty for France against England in November.
However Wenger insisted Clichy would not be risked from the start against the Spaniards.
Captain Thierry Henry started on the bench at the weekend against Tottenham, along with Cesc Fabregas, but both are in contention to start, while midfielders Freddie Ljungberg and Alexander Hleb also come back into the equation after being rested.
Jose Antonio Reyes is available again following a one-match European ban, but Togo striker Emmanuel Adebayor is cup-tied.
England full-back Ashley Cole (ankle) is still not yet fully match fit.
