However, Newcastle have started this season in the second tier in impressive fashion with three wins and a draw and they can claim top spot in the Championship table by beating Leicester at St James' Park on Monday.
The Bulgarian's last-gasp strike, coupled with Arsenal's 2-2 draw at West Brom, allowed United to restore a cushion at the top of the table that had been damaged by defeats at Chelsea and Liverpool.
Meanwhile, Tunisia snatched a 2-2 draw in Nigeria thanks to a 90th-minute Oussama Darragi goal in a top-of-the-table Group B clash, to maintain a two-point advantage with two matches left.
