Newcastle had not won away from home in the Premier League since 2015 and Sunday's disjointed affair seemed destined to end goalless until Lascelles headed in after 76 minutes. He had been in such pain this week that he hadn't been able to travel to training.
Wilfried Bony, another deadline-day signing, had replaced Sanches by that stage but starved of service, the Ivorian had little chance to make an impact on the game as Swansea ran out of ideas.

"We made too many mistakes, we gave the ball away too often".
"But the ins that we got are very good and I am pleased with the size of the squad".
"Very frustrating. I'm finding it hard to understand why I saw what I saw".

Instead, it was left to Lascelles to get free at a corner and head the Magpies to their second straight win of an improving league campaign.
