Manchester United head to Belgium amid heightened security concerns in the wake of the Dortmund bomb attack, leading Anderlecht winger Massimo Bruno to call for everyone to stick together ahead of the Europa League quarter-final.
Three explosions occurred on Tuesday evening as Borussia Dortmund's team bus made its way to Signal Iduna Park, with defender Marc Bartra requiring surgery after an attack that saw the Champions League quarter-final first leg against Monaco postponed until the following day.
European governing body UEFA pledged in a statement to review security arrangements for Wednesday's matches and said 'procedures will be enhanced accordingly wherever needed'.
