Moussa Dembele took care of most of the drama at the deadline of the transfer deadline, when Celtic sold the peak to Lyon for almost £ 20 million after an initially rejected bid had raised public opposition from the Frenchman.
Celtic boss Brendan Rodgers refused to sanction the deal on Thursday without an adequate replacement drafted.
But the club made a turn around after Rodgers felt Dembele's antics on social media and the training field threatened the team's culture prior to Rangers' visit on Sunday.
It was a fitting end to a difficult transfer window for Celtic, that Rodgers missed out on two of his three highest goals and led a striker down, plus an unfortunate player in Dedryck Boyata, who missed a move to Fulham and did not see no move to the continent comes forward.
Celtic completed two deals by the deadline, although the former West Brom and Kilmarnock midfielder Youssouf Mulumbu signed a two-year contract and Leicester defender Filip Benkovic concluded a seasonal loan.
Rangers completed a season-long loan deal for Nottingham Forest and England Under-21 center-back Joe Worrall while Albanian winger Eros Grezda signed a four-year deal after his relocation from Croatian side Osijek, depending on the paperwork being completed.
Manager Steven Gerrard was looking for a fifteenth summer signing until late in the window and Rangers were deemed to have rejected a West Brom approach to loan James Tavernier on loan in January.
Gerrard warned clubs interested in Alfredo Morelos: "Do not waste your time" and Bordeaux signed another striker in the midst of messages they intended to go back to the Colombian.
Reports claimed that Aston Villa had failed to lend Aberdeen-based Aberdeen defender Scott McKenna for a billion dollar bet in January.
Hamilton was the busiest club and signed four players including James Keatings from Dundee United. Midfielder Scott Martin arrived from Hibernian, defender Matthew Kilgallon from Bradford and the 29-year-old Molde forward Fredrik Brustad was on loan.
Elsewhere in the Ladbrokes Premiership, St Mirren Ryan Edwards signed for a seasonal loan from Hearts after the former midfielder of Partick Thistle failed to form a first team after his summer trip to Tynecastle.
Kilmarnock manager Steve Clarke lost one player – presumably Robbie Muirhead, who signed for Dunfermline from MK Dons – but completed the signing of the loan from Wolves, Bright Enobakhare, on loan until January. The 20-year-old scored two goals last season in 26 appearances for Wolves.
Dundee signed Celtic left back Calvin Miller and Preston center-back Andy Boyle on loan, but Hearts and Hibernian could no longer get deals over the line.
The latter released Danny Swanson for the expected return of the midfielder to St Johnstone.
