Former Benfica and Chelsea fullback Scott Minto believes Arsenal will be too strong against Porto.
The Gunners meet Porto in the first-leg of their Champions League quarterfinal.
"FC Porto has a strong brand and a lot of experience in the Champions League and will never stop fighting," Minto told O Jogo.
"But I feel that Arsenal will pass in both legs, because they have a better team and better players. But pay attention, if they want to beat FC Porto they will have to give their best, nothing can make it easier, (Sergio) Conceio knows how to overcome himself and make players overcome themselves.
"These were also his principles as a player."
