Borussia Dortmund prepared for the beginning of their latest Champions League campaign by soaking up the early autumnal sun in a London park.

The 2013 finalists face Tottenham at Wembley on Wednesday night, the scene of their defeat to domestic rivals Bayern Munich four years ago.

New coach Peter Bosz, fresh from taking Ajax to the final of the Europa League, will be hoping he can take Dortmund one step further than Jurgen Klopp managed.

But having been placed in a group alongside Real Madrid, Spurs and Apoel Nicosia they will have to be at their best to progress to the last 16.

Bosz will be reunited with Davinson Sanchez at Wembley, who joined Mauricio Pochettino's side from Ajax in a £42m deal last month.

The 21-year-old started in Spurs' win over Everton on Saturday and is expected to continue at Wembley.

'He is a good player even though he is still young,' Bosz said of Sanchez.

'What surprised me was that he played the final of the Copa Libertadores, which he won, and without any vacation he came to us and after one week he played the whole season, never injured and always working hard in training.

'I think he became a better player, especially with the ball. Without the ball he is a monster - strong in the air, fast - but with the ball at Ajax, we had a certain way of playing and he adapted.'

Manager Peter Bosz's side are top of the Bundesliga and undefeated in the league this season
