Manchester United left it very, very late, but Ole Gunnar Solskjaer was given the extra striker he wanted in the form of Odion Ighalo.
With a move for Bournemouth's Joshua King dead in the water, the Red Devils focused their efforts on a loan deal for the 30-year-old, who has been playing for Shanghai Shenhua since last February.
Ighalo's deal, which Omnisport understands does not include a purchase option, will give Solskjaer another option up front during the injury absence of Marcus Rashford. He is expected to travel to England in the coming days.
Ighalo was far from the only major deal to be concluded late in the transfer window, though, as West Ham just managed to finalise the signing of Jarrod Bowen from Hull City for a reported initial fee of £22million.
Aston Villa also announced a new striker signing about 10 minutes before the window closed, Borja Baston joining on a free transfer from Swansea City.
Elsewhere in England, Tariq Lamptey took the decision to leave Chelsea and sign for Brighton and Hove Albion on a contract until 2023. The Seagulls have also brought back Alexis Mac Allister from Boca Juniors, where he was on loan.
Deadline day was as notable for the deals that looked to have fallen through as those that were completed.
Paris Saint-Germain ruled out allowing Edinson Cavani to leave, as a host of clubs fancied taking the Uruguayan off their hands, while Chelsea refused to let France striker Olivier Giroud depart Stamford Bridge.
Tottenham was among the clubs keen on Giroud, but Jose Mourinho looked like missing out on the striker he wanted to strengthen a front-line depleted by the loss of injured England captain Harry Kane.
Real Madrid boss Zinedine Zidane said Gareth Bale would not be leaving the Santiago Bernabeu.
Manchester United remained linked with Bournemouth forward Joshua King, but time was running out for Ole Gunnar Solskjaer to add new faces to his Old Trafford squad.
United made one signing, but it was a low-profile deal as England Under-20 goalkeeper Nathan Bishop arrived from third-tier Southend United.
Arsenal brought in defender Cedric Soares on loan from Southampton.
