Arjen Robben is a major doubt for Bayern Munich's Champions League clash with Juventus on Wednesday, coach Pep Guardiola has said.

Robben missed Bayern's final training session suffering from a cold, and Guardiola told a news conference: "I don't know if he can play tomorrow."

The 32-year-old Netherlands winger is likely to sit out what Guardiola called "a final for both teams" after the first leg of the round-of-16 clash ended in a 2-2 draw.

"It's a huge match," the coach said. "The 2-2 is a result, a 5-0 would have been better, but it was not possible."

Juventus will be without Claudio Marchisio and Paulo Dybala at the Allianz Arena, while Giorgio Chiellini did not make the trip across the Alps, but Guardiola said he did not believe that would make the Serie A leaders any less dangerous.

"They still are Juventus," he said. "Maybe [Alvaro] Morata plays, and he's even more dangerous on the counter-attack than Dybala.

"The situation has not changed. They have won one thousand million titles with their mentality, and are a dangerous team."

Guardiola has been under pressure to win the Champions League, as his predecessor Jupp Heynckes did in his final year at Bayern, since joining in the summer of 2013.

"I accept the pressure," he said. "We'd be satisfied if we win tomorrow, and we'll think about what we can do better if we lose.

"We all try to win the Champions League. We've got fewer injuries than last season. But it will get difficult should we lose tomorrow, for a few days."

Guardiola said the stubborn Juventus defence would present a challenge for his side, adding: "They can get ten players behind the ball and defend really well. I admire that. I don't like it, but I admire it.

"I expect a match like in the first leg, where small details will decide the tie."

Speaking to reports in Munich on Tuesday, Bayern attacker Robert Lewandowski said he had been impressed with the way Juventus recovered from being 2-0 down in the first leg.

"Italian teams always fight until the end," he said. "They never lose their cool. We need to be patient, but can't play for a draw.

"Juve have great attacking players, and when they sense a chance to score they'll shoot."
