O Jogo has learned that Borussia Dortmund are weighing up a summer bid for Sporting Lisbon goalkeeper Rui Patricio.
The Millionaires are slowly preparing for life without veteran keeper Roman Weidenfeller and they seem to have chosen the Portugal international as his replacement.
Borussia Dortmund have expressed their interest in signing the 27-year-old shot-stopper, although they could face stiff competition from Liverpool, Monaco and Atletico Madrid.
Rui Patricio has so far resisted temptation to quit Estadio Jose Alvalade in spite of the heavy interest from abroad, but he may be ready to consider his options at the end of the season.
The experienced goalkeeper has long been regarded an important player for both club and country, and he has spent his entire career so far with Sporting.
But, with interest in his services gaining momentum as the summer transfer window draws closer, a summer exit could be on the cards.
