Sporting CP are eager to do quick business with Chelsea this week over Matheus Nunes' sale.
A Bola says Chelsea are making their move for Nunes after he failed to agree a move to Wolves.
The highly-rated Sporting midfielder is valued at £43m and Chelsea have no problem paying that.
It is even suggested he could seal a move by the end of the week with Sporting keen to use the money on other targets.
Nunes would arrive as potentially a long-term successor for N'Golo Kante as he enters veteran status.
