Chelsea boss Jose Mourinho has received encouragement in his pursuit of Porto striker Jackson Martinez.

Tuesday's defeat to Sunderland underlined Mourinho's summer assessment of his squad that they needed more ammunition to dominate at the top level.

The Daily Mail says Porto need to raise funds again following their exit from the Champions League, they want £35million for a 27-year-old who Liverpool considered three years ago when Martinez was playing for Chiapas in Mexico.

He has scored 13 goals in 19 games for Porto this season but only one came in the Champions League - the 2-1 home defeat to Atletico Madrid.
