Former Roma Coach Fabio Capello warns his old side not to underestimate Porto - “even here, watch out”.
The Giallorossi finished second in their Champions League group, and many felt they were handed a kind draw in the Last 16.
However, the Portuguese champions have dropped just two points in Europe this season, and have won 11 of their 13 league games.
“It’ll take a great Roma to go through,” Capello warned, speaking to Gazzetta dello Sport.
“Porto are going very well in the league, and have interesting players like the midfielder [Moussa] Marega.
“They play well and have eight Brazilians in their squad. Even here, watch out.”
