Monday was a key day in the development of Jadon Sancho's future, amid links with a move to Manchester United this summer.
Dortmund chief Michael Zorc insisted United have no chance of signing Sancho now after he jetted off with his team-mates to Switzerland for a pre-season training camp. However, the Red Devils still remain hopeful of landing the England international with the two clubs remaining at loggerheads over his £108million valuation.
Dortmund's valuation of the England winger continues to be a stumbling block along with the players' wages and his agent's fees. United are determined not to repeat the mistakes of the past few years which has seen them make some costly mistakes in the transfer market.
United manager Ole Gunnar Solskjaer could be looking at attacking alternatives to Sancho
Speaking on Monday, Zorc said: 'We plan with Jadon Sancho. He'll play for us next season. The decision is final. I think that answers all of the questions.'
Zorc also went on to reveal that the club secretly renewed Sancho's contract until 2023 a year ago and as such, Ole Gunnar Solskjaer and his staff could start to look elsewhere as they hunt an attacking talent to add to their ranks.
Though Marcus Rashford, Anthony Martial and Mason Greenwood have all proved themselves capable of operating from out-wide, all three favour a role through the middle.
So, if the Sancho deal does indeed fall through, who are United's alternatives in an attacking position on the flanks? Sportsmail takes you through all the potential options...
The Bayern Munich forward, who is on a streak of nine-straight league titles across three different teams, has already racked up quite the array of top European clubs in his career, despite only just reaching his peak years at 24.
The former PSG and Juventus winger - who missed the Champions League last-16 second leg victory over Chelsea on Saturday with a muscle problem - is not always an automatic starter at the Allianz Arena, and this season has fought for a place against the likes of Serge Gnabry, Ivan Perisic, Thomas Muller and Philippe Coutinho.
With Leroy Sane signing too, the attraction of regular first-team football could be key for Coman, with the Frenchman's direct style of play, as well as skill and prowess in one-on-one situations out-wide, proving attractive to Solskjaer.
With experience in Ligue 1, Serie A and the Bundesliga already, Coman certainly wouldn't be fazed by a move to Old Trafford, which could materialise via a loan deal with an option to buy.

Formerly of Bayern himself, Juventus winger Douglas Costa presents an all-together different threat from out-wide - but by no means any less effective.
The left-footed Brazilian is believed to be preparing himself for a move away this summer, after starting just six league games all season as the Old Lady retained their Serie A title under the now-sacked Maurizio Sarri.
It remains to be seen whether
