Jordi Alba and Sergio Busquets paid a visit to former Barcelona team-mate Marc Bartra as he continues his recovery from a broken wrist suffered during last week's attack on Borussia Dortmund's team bus. Spain centre-back Bartra underwent surgery after the Dortmund squad was targeted by three explosions on their way to last Tuesday's Champions League quarter-final against Monaco at Signal Iduna Park. A window on the bus shattered and Bartra also had debris removed from his hand, while the match was pushed back a day and Monaco claimed a 3-2 first-leg advantage. Alba posted a picture of the trio on Instagram and said: "What a joy to see you and to share laughs together, my friend." In an Instagram post of his own last Friday, Bartra described the ordeal of the attack as "the longest 15 minutes of my life".     –Agencies
