Roma boss Luciano Spalletti says he doesn't want any nervous players on his team ahead of a crucial Champions League playoff second leg against Porto this week.
The Italian side will be without defender Thomas Vermaelen after his red card in the first leg, a 1-1 draw at the Estadio do Dragao last week.
But with a spot on the group stage in the balance at the Stadio Olimpico, Spalletti urged his team to go on the attack.
"We want to take the game to them -- we are not going to leave it down to fate, we want to determine the result," Spalletti said in his prematch news conference.
"We need to go out there with our heads high and try to win the game from the off, not wait for them to play it around our box looking to score.
"If we struggle dealing with fear, risk and danger then that means we're afraid of dealing with success too. And if that's the case for a player then they don't belong at Roma.
"If they get nervous about a match they've wanted for eight months then they don't belong at Roma. They should want to play it.
"They shouldn't feel stressed about trying to manage the result. If they're scared, they're not for us."
A Felipe own goal put Roma ahead in the first leg, but after Vermaelen was sent off before the break, Porto were able to equalise.
Roma will have a slim away-goal edge in the second leg, but Spalletti said his side, coming off a 4-0 win over Udinese at the weekend, can play better than they showed in Portugal.
"Given our experience and ability in managing games, we weren't good enough after we took the lead," he said.
"We played below our level after the break, but even though we were a man down we still pressed them in their half of the pitch.
"I expect to see that again. It needs to be a trait we display every time we get the chance to wear the Roma colours.
"The lads showed me what I wanted to see against Udinese. Udinese were a very physical opponent and that's true of Porto too - in the penalty box we were up against some big guys."

Spalletti was coy about his lineup plans, but there was some good news as defender Antonio Rudiger returned to training on Monday, two months after tearing the anterior cruciate ligament in his knee.
The 23-year-old, who signed a permanent deal with Roma this summer, will still be unavailable for some time as he begins to rebuild his fitness.
