Stoke winger Xherdan Shaqiri believes Basle can cause an upset when they visit Old Trafford for their Champions League Group A clash with Manchester United on Tuesday.
Shaqiri, who was a product of Basle's academy, has claimed the Swiss champions are capable of getting a result if they are prepared to take risks against United's 'vulnerable' defence.
The Switzerland international got an assist against Jose Mourinho's side in their 2-2 draw on Saturday, crossing for Eric Maxim Choupo-Moting to score his second and level up the scores.
Basle go into the game with United as heavy underdogs, especially following their 2-1 home defeat to Lausanne at the weekend which left them without a win in three games.
