Massimiliano Allegri was critical of Juventus' second-half performance after they reached the Europa League quarter-finals with a 2-0 win at Freiburg on Thursday.

Juve built on their 1-0 first-leg advantage as Dusan Vlahovic converted a first-half penalty after home defender Manuel Gulde was controversially sent off for handball inside his own area.

Federico Chiesa added a late second after entering the fray as a substitute, as Juventus maintained their bid for a first major continental title since they won the Champions League in 1996. 

However, Allegri was displeased with Juventus' performance after Freiburg went down to 10 men, saying the Bianconeri must improve if they are to progress further in the competition.  

"The team got a good result as we progressed. We made a lot of mistakes in the second half with our ball handling, and we need to improve," he said at his post-match press conference.

"We can't play a second half like this against a team of 10. We were made to defend our own box. The second half should have been better. We need to work; we made a lot of wrong decisions.

"Against 10 we lowered our attention and pace. The result is good – excellent even – but let's not get excited because we're in the quarter-finals. We have to think about what we did in the second half and improve."

Chiesa's stoppage-time goal – a driven strike which found the net via the foot of the post – was just his second since returning from an anterior cruciate ligament injury in November, and the Italy international is looking to find consistency in the coming weeks.

"My first thought is to be available to the coach. Unfortunately I haven't been there in the last few games," he said. "There's still a bit of discomfort, but I'm working even harder to be more ready.

"Unfortunately my father [former Italy striker Enrico Chiesa] had similar injuries. It's a path of great obstacles to come back, but even after that, the journey continues. I just have to stay calm."

Meanwhile, the decision to send Gulde off after his outstretched arm was struck by Federico Gatti's shot infuriated Freiburg boss Christian Streich, as did a failure to punish Wojciech Szczesny for seemingly picking up a Manuel Locatelli back-pass.

"We were brave, we went for it," the Freiburg boss said. "Then there was the situation with the red card and the penalty. That was of course a difficult situation for us.

"I'm speechless. In both games, after every foul, a Juve player plays the ball away. Always. It's a complete mystery to me. 

"Then there's the intentional back-pass that isn't blown. It's difficult to accept. Something that was crucial was let go."

Christian Gunter was lost for words after his Freiburg side were thumped 6-0 by Wolfsburg on their return to Bundesliga action on Saturday.

Freiburg entered the two-month break second only to Bayern Munich in the table after winning four of their final five league games of 2022.

But any thoughts of possibly rivalling 10-in-a-row champions Bayern were put into perspective by Wolfsburg at the Volkswagen Arena.

Christian Streich's side were behind after just 59 seconds through a Patrick Wimmer strike, before Jonas Wind's double put the hosts in complete control before half-time.

Yannick Gerhardt and Ridle Baku joined the scoresheet in the second half, and Luca Waldschmidt beat Mark Flekken from the penalty spot to complete the scoring.

"I don't have any explanation. It wasn't expected. We have to look at what went wrong," Freiburg captain Gunter told Sky Sport.

"It's extremely painful to start like this in 2023. Everything came together for them; it was a very bad day for us."

Freiburg's heavy loss sees them drop to fourth below Eintracht Frankfurt and Union Berlin, with all three sides five points behind leaders Bayern.

Reflecting on a chastening day for his side, Freiburg head coach Christian Streich said: "We lost 6-0 and didn't have a chance.

"After the first minute, we got to know how good Wolfsburg are. In the end, we lost 6-0. What can I say? Maybe it's best I don't say anything."

Wolfsburg's win was their fifth in a row in Bundesliga – their best run since 2014 when winning six in a row – and moves them within four points of the Champions League spots.

"We got off to a very good start," Wolfsburg coach Niko Kovac said. "From our second shot, we scored our second goal, then it was a sure-fire success from there.

"Basically, you can't go wrong from there. I'm happy with the way this team is developing."

Freiburg reached the DFB-Pokal final for the first time in their history with a 3-1 semi-final win at second-tier Hamburg.

Goals from Nils Petersen, Nicolas Hofler, and Vincenzo Grifo fired Freiburg into a commanding half-time lead as the visitors produced a scintillating counter-attacking display.

The Bundesliga's third-best defensive outfit then held on comfortably after the break, despite Robert Glatzel providing a late consolation for the hosts, and Freiburg will meet either RB Leipzig or Union Berlin in next month's final.

11 years after first joining the visitors, head coach Christian Streich continues to make history, with Freiburg's dreams of cup glory and a top-four Bundesliga finish remaining in their sights.  

Hamburg fell behind after just 11 minutes when Petersen headed home after a goalmouth scramble, with a quick VAR check ascertaining Roland Sallai was not interfering with play.

That goal gave Freiburg a huge boost, and they doubled their lead within five minutes when Hofler's long-range strike cannoned off Sebastien Schonlau and into the roof of the net.

Hamburg almost responded when Anssi Suhonen forced a save from Mark Flekken, but were out of the contest after 35 minutes when the VAR awarded Freiburg a bizarre penalty, with Vincenzo Grifo smashing home from the spot after Moritz Heyer clumsily kicked Nico Schlotterbeck in the neck.

Suhonen had a cool finish ruled out in a marginal offside call as Hamburg's nightmare half drew to a close, before Sallai rippled the side netting with a fierce strike shortly after the break.

The 2.Bundesliga team took the game to Freiburg in the second half, with Sonny Kittel's deflected volley drawing a decent save from Flekken after 67 minutes.

Hamburg were finally rewarded for their improvement when Glatzel nodded a consolation goal after 87 minutes, and Freiburg's Ermedin Demirovic struck a post from range as the visitors claimed a historic win.

What does it mean? Fantastic Freiburg reach new heights

Freiburg had never previously reached the German domestic cup final, losing to Stuttgart on their only previous semi-final appearance in 2013. 

Streich's men, however, will compete for their first major trophy in May's final, and could beat their highest-ever Bundesliga finish of fifth (in 2012-13) as they continue to chase a top-four spot.

Cup hero Petersen sets the tone

With a packed Volksparkstadion producing a boisterous atmosphere, Freiburg needed an early goal to quell any nerves, and got one through Petersen's header. The 33-year-old has now scored 12 in the competition, with no other player scoring more (Alexander Iashvilli also has 12).

Visitors make fast start count

After putting their hosts to the sword before the break, Freiburg have now scored six first-half goals in their four DFB-Pokal games this season, with only RB Leipzig scoring as many in the competition.

Streich's team also became just the second to hit three first-half goals in an away DFB-Pokal semi-final. Bayern Munich are the other team to do so at Schalke in 1984.

What's next?

Hamburg will look to revive their slim hopes of promotion from the 2.Bundesliga at Jahn Regensburg on Saturday, while Freiburg host Borussia Monchengladbach on the same day.
