Fernando Torres has admitted that he needs to do more to justify his price tag, Sky Sorts understands.

The Spain international has scored just 37 goals in 139 appearances since switching from Liverpool half-way through the 2010/11 campaign.

He was the clubs to scorer last term with 23 goals, though he has just scored twice this time around, and has failed to find the net in any of his five league appearances.

The 29 year old, who is currently side-lined with a knee injury, has admitted that his return in the 2012/13 campaign ‘should be the minimum’ before adding that he believes the criticism which he has received have been over the top.

Meanwhile, Wolfsburg have confirmed their interest in signing out of favour midfielder Kevin De Bruyne, according to the Metro.

The Belgium international has been somewhat cast aside by manager Jose Mourinho since turning in a poor performance against Swindon Town in the third round of the League Cup.

He impressed in a season-long spell in the Bundesliga last term, scoring ten goals in thirty-four appearances for Werder Bremen.

Last season’s Champions League runners up Borussia Dortmund were also linked with the 22  year old but this week withdrew their interest.
