The former Atletico Madrid striker is expected to shake off a slight ankle injury and face Werder Bremen in Grenchen.

Manager Rafael Benitez said: "We had to wait for Fernando because he started training after the other players.

"We also needed to check his ankle but I think he'll be okay for our next game."

Torres could link up with former Bayer Leverkusen striker Andriy Voronin. The Ukrainian marked his first start of the club with a fine display in the defeat of Crewe on Saturday in a friendly.

Benitez said: "We know that Voronin is going to be another option for us. He has good game intelligence, he plays well between the lines and he has a lot of quality."
