Manchester United are locked in talks with Porto for the signing of left-back Alex Telles.

​Porto push Man Utd to offer more money for Alex Telles.

The Brazilian is out of contract next summer and the Portuguese club want to sell to raise funds.

United are close to getting a deal done for the 27-year-old, having agreed personal terms

But according to Correio de Manha, Porto have raised their transfer demands due to several pre-agree clauses.

They owe Galatasaray a sell-on clause of 10 per cent as well as fees to super agents Jorge Mendes and Pini Zahavi.

To cover the costs, the Portuguese have raised their asking price from €20m (£18m) to €27m (£24.7m).

Telles will reportedly sign a five year deal and earn £3.6 million per year if he signs with United.
