Tottenham Hotspur know that only victory at Camp Nou will be enough to guarantee their place in the last 16 of the Champions League when they face Barcelona on Tuesday night.
Spurs' hopes of reaching the knockout rounds looked bleak at the halfway stage, but they go into the final matchday sitting second on head-to-head away goals above Inter Milan.
A win would therefore seal their progress, but they will be consigned to Europa League football in the New Year if they do not at least match Inter's result against PSV Eindhoven.
Here, Sports Mole looks at how Mauricio Pochettino could line his side up for the crucial showdown.
Out: Mousa Dembele (ankle), Erik Lamela (thigh), Davinson Sanchez (hamstring), Victor Wanyama (knee), Juan Foyth (ineligible), Vincent Janssen (foot)
Doubtful: Serge Aurier (knock), Kieran Trippier (groin)
Harry Kane and Christian Eriksen were left out of the starting lineup for the weekend win over Leicester City, but both will return to the team on Tuesday night.
Dele Alli and Son Heung-min - who got Tottenham's goals at the King Power Stadium - should also start at Camp Nou, but the injury concerns are beginning to pile up for Pochettino.
The biggest dilemma could come at right-back, with Serge Aurier limping off against Leicester to join Kieran Trippier on the sidelines. Both are doubts for this match, which could see Kyle Walker-Peters thrown into the deep end.
Juan Foyth was not included in Tottenham's Champions League squad and so Jan Vertonghen and Toby Alderweireld are the only centre-back choices, with Davinson Sanchez among those sidelined by injury.
