Graeme Murty saw his Rangers side earn a narrow 1-0 win over Brazilian outfit Atletico Mineiro on Thursday night at the Orlando City Stadium in the Florida Cup - but Ibrox fans have blasted Dalcio's performance during the victory.
Gers boss Murty fielded a side that included youngsters Aidan Wilson and Serge Atakayi as well as new signings Sean Goss and Jamie Murphy before making 10 changes at half-time.
With the score goalless at the break, in-form attacker Josh Windass popped up in the 68th minute to curl an excellent effort into the back of the net in what had been an equal match throughout the contest.
Murty, 43, handed outcast Dalcio a start in the unusual position of left-back, as the Benfica loanee remains with the Gers despite making just three appearances for the Gers - totalling in 134 minutes of competitive first-team action this term.
Rangers fans took to Twitter to express their dismay at the 21-year-old's performance, with no sympathy reserved for the Portuguese winger signed by Pedro Caixinha despite playing out of position in defence.
One fan even described the winger as a "waste of a jersey".
Only seen the first half of the Rangers game last night and Dalcio.... waste of a jersey— Craig Cunningham (@craigoooc1) January 12, 2018
Goss looks decent, Atakayi has potential, the penny seems to have dropped with Windass and great effort from Halliday.— Graeme (@rangersallover) January 12, 2018
A few players should be moved on, MOH won't do and Dalcio is a waste, get him back to Lisbon.
Halliday with a great defensive header kept us in the lead.— Rob Norrie (@RNorrie90) January 12, 2018
Dalcio was really poor, we should send him back to Benfica.
Thought Herrera wasn't too bad. Tried to link play at least. If the rumours are correct of 1.2m for him I'd be happy. Dalcio is just no use for us clearly.— Allan (@AllanRFC_) January 12, 2018
I may be overreacting but if Dalcio and Herrera can't even do it in the Florida Cup we need to get rid of them asap.— The Staunchest (@TheStaunchest) January 12, 2018
First half: Danny Wilson, Goss, Murphy, Morelos played well.— Graham Dorrans Loyal (@Dorrans_WATP) January 12, 2018
Second: MOH, Halliday, Candeias, Windass played well.
Dalcio.... was emm Dalcio.
Haliday and o halloaran looked decent , Herrera , Dalcio and niko need to be moved off the wage bill ASAP— Iain Macmillan (@scalstriker7) January 12, 2018
