Real Madrid have joined the interest in Sporting CP winger Gelson Martins.
Real will send scouts to Lisbon on Tuesday to keep an eye on Gelson, reports Correio da Manha.
The winger, who shone at the Bernabeu in Sporting's narrow 2-1 defeat at Real Madrid this season, has also been linked with Barcelona, Manchester United and Bayern in recent weeks.
His performance in the Spanish capital last month caught the eye of Bernabeu figures too and the European champions are planning to send representatives to Portugal to watch the midfielder in action during Sporting's Champions League match with Borussia Dortmund.
