Paris Saint-Germain may have lost to a sensational Erling Haaland double on the night, but they did claim an away goal - Neymar slotted home after some fine work and a low, hard cross from Kylian Mbappé - and will have the advantage of playing the crucial second leg in Paris on 11 March.

Tuchel: 'We have everything needed to win'

It was an intense encounter at Signal Iduna Park, with precious few chances in an evenly matched first half before PSG began to push harder on the hour-mark. This slight shift in the balance of the match brought about a flurry of goals, all of which showcased lightning speed and precision - but two of which were scored by Dortmund's 19-year-old Norwegian star Haaland.

"Maybe we played with the fear of making that little mistake, and when you focus too much on mistakes, they eventually happen," offered Tuchel after the match against his former club. "We lost confidence by losing the ball easily on several occasions; we complicated the task at hand for ourselves.

"We lacked a bit of rhythm, and we need to find that in order to be at our best for the return leg at the Parc des Princes. We are losing 2-1, but we can do a lot better than we did this evening. There is a second half to play at the Parc, we have everything needed to win."

Neymar: 'It wasn't my choice'

Most had expected Tuchel to field his patented 4-4-2 with at least three of his Quatre Fantastiques, but instead he opted to mirror BVB's 3-4-3, leaving Mauro Icardi and Edinson Cavani - both of his out-and-out strikers - on the bench, with Mbappé flanked by Neymar and Angel Di Maria in a front three.

The attacking trident was well muzzled by Dortmund's tightly organised defensive sector for long stretches, and Neymar - brought back into the side after a four-match absence - struggled to make an impact for most of the match.

"It's hard to go four games without playing. Unfortunately it wasn't my choice, it was something the club did, it was something the doctors did, they made the decision, I didn't like it," said the Brazilian. "We had a lot of discussions about it. I wanted to play, I felt good, but the club was afraid, and I'm the one who suffers in the end."

The drawing Bordeaux

Tuchel and his men now turn their attention to Sunday's home clash with Bordeaux in Ligue 1 Conforama - their first chance to re-work things ahead of the all-important second leg at home to Dortmund on 11 March.
