Borussia Dortmund look set to rival Schalke for Manchester United target Xherdan Shaqiri, [football] direct news understands. The Swiss international has struggled to make an impact at the Allianz Arena since joining from FC Basel, where he had become regarded as one of the most promising young players in Europe. The 22-year-old has been linked with United since last summer but a German football source now believes he is a priority signing for the Bundesliga sides. Sacked United manager David Moyes had Shaqiri watched on several occasions this season with the former Everton boss readying a 30m bid for the star before he received the chop. But with all the uncertainty at United following his departure it remains to be seen whether the new manager will want Shaqiri.
