Barcelona were left ruing the cost of individual errors after their 3-3 draw with Inter Milan left them on the verge of Champions League elimination at the group stage for the second year running. Gerard Pique played Nicolo Barella onside and let the ball travel through to him to level for Inter at 1-1, with Sergio Busquets softly ceding possession for the Italians' second goal at Camp Nou, scored by Lautaro Martinez. Both players are club veterans and coming towards the end of their careers in Barcelona, a process which some supporters felt should have been sped up in the summer.
