DORTMUND KEEN ON PERMANENT DEAL FOR IAN MAATSEN - SOURCES

 Borussia Dortmund want to sign Ian Maatsen on a permanent basis but are reluctant to meet Chelsea's £35 million ($44.7m) valuation, sources have told ESPN.

The 22-year-old joined Dortmund on loan in January and became a key member of Edin Terzic's team, playing every minute of their seven Champions League knockout matches which culminated in last weekend's final defeat to Real Madrid at Wembley.

Prior to that game, Maatsen publicly admitted his future was uncertain and sources have told ESPN that Dortmund are keen to extend his stay in Germany after the full-back made 24 appearances across all competitions, scoring three goals.

Chelsea are looking to recoup money through outgoing transfers to maintain compliance with the Premier League's Profit and Sustainability Rules and are willing to allow a number of fringe players to leave the club including Maatsen, Romelu Lukaku and Trevoh Chalobah.

However, sources have told ESPN that Chelsea's hopes of securing a lucrative deal for Maatsen's transfer is considered a stumbling block with Dortmund believed to be readying an opening offer considerably lower than that figure. One source suggested their initial offer would likely be between £20m to £25m.

Any deal that Chelsea want to form part of their 2023-24 accounting year must be completed by June 30 and Dortmund are hopeful that theoretical deadline could help them negotiate a lower transfer fee.

DORTMUND ENDS 'ROLLERCOASTER' DAY IN CHAMPIONS LEAGUE SEMIS

 Marcel Sabitzer scored late and set up two goals to send Borussia Dortmund into the Champions League semifinals with a helter-skelter 4-2 win over Atlético Madrid on Tuesday.

After losing the first leg of their quarterfinal 2-1 in Madrid, Dortmund had to come from behind twice over two legs to advance 5-4 on aggregate.

Julian Brandt opened the scoring to level the tie before Sabitzer set up Ian Maatsen to give Dortmund a 2-0 lead on the night.

Atlético coach Diego Simeone responded with three changes at the break and they all paid off. A Mats Hummels own goal and goal from substitute Joaquín Correa put the Spanish side back in front on aggregate.

Then Sabitzer set up Niclas Füllkrug in the 71st minute for the Germany forward's first goal after nine scoreless games, and Sabitzer scored himself three minutes later to send Dortmund into the last four.

"That was a rollercoaster, a really great evening," Dortmund chief executive Hans-Joachim Watzke said. "It's not always like that for Borussia Dortmund. The last time we were in the semifinals was in 2013. This is a great day for all Borussen."

Dortmund will face Paris Saint-Germain again in the semifinals. PSG progressed to the final four with a 4-1 win at Barcelona. And Dortmund coach Edin Terzic feels his side, who won the Champions League in 1997, are now better prepared to face the French champions, after the Germans lost away and drew at home in the group stage.

"Our first game against them wasn't good. In the second game, we adjusted to them better and were closer to victory. I think we're a better team today than we were against them in the group stage," Terzic said following the win over Atletico.

The final will be played June 1 in London, where Dortmund lost the 2013 final 2-1 to bitter rival Bayern Munich.

Tuesday's win stretched Dortmund's unbeaten run at home in the Champions League to 10 games.

"We were close to tying the game, but they were superior, and when a team is superior they should be congratulated," Simeone said.

Atlético needed goalkeeper Jan Oblak at his best. He denied Brandt, then Karim Adeyemi, before Brandt finally made the breakthrough in the 34th, firing a powerful shot in off Oblak's leg from a difficult angle after eluding former teammate Axel Witsel.

Sabitzer then combined with Maatsen, who surged past two defenders and fired the ball inside the far post in the 39th. It was the Dutch defender's first Champions League goal.

But Atlético only needed four minutes after the break to level the tie when Hummels' attempted clearance of Mario Hermoso's header ended in his own net.

Correa should have scored shortly afterward when he nudged the ball wide. Simeone - dressed sharply in a black suit - flopped to the ground in frustration.

Correa made no mistake in the 64th when he fired in a rebound after his first attempt was blocked.

It put the visitors back in front, but Sabitzer was involved in both goals as Dortmund struck twice in three minutes to send the home fans wild.

"It was a crazy game for the fans and for us. A great game for us, for our fans and for all football fans around the world," Brandt said after receiving his man-of-the-match award.

"It's going to be very serious now against Paris. We played well against them at home in the group stage, but not well away. We want to do better now and, of course, reach the final."

For striker Niclas Fullkrug, who also got on the scoresheet, the Champions League semifinals will be a new experience.

"I've never played at this level before and I'm very proud to be in the semifinals of the Champions League with my team," Fullkrug said. "Things will certainly be different against Paris than in the group stage."
