LONDON (AFP) - Tony Pulis's West Bromwich Albion tenure began with a 7-0 demolition of non-league Gateshead in the FA Cup third round on Saturday, Jan 3, 2015, while Leicester City eliminated managerless Newcastle United.
Pulis was appointed as West Brom's new head coach on New Year's Day following Alan Irvine's sacking and he watched his new charges cruise into round four, with Saido Berahino scoring four times.
The England Under-21 striker, who has been linked with Liverpool, opened the scoring in the 42nd minute at The Hawthorns before Victor Anichebe added a second with a solo goal in first-half injury time.
Berahino produced two classy finishes early in the second period to complete his hat-trick, with Chris Brunt and James Morrison adding two more goals before Berahino struck again to take his tally for the season to 13.
"Saido Berahino is a very talented boy," Pulis said. "There is always going to be transfer speculation and you can see why. He has great pace, great balance and scores goals.
"But when I came in here the chairman had not received any offer for him and we will try our damnedest to try and improve him."
While West Brom began their new era in confident fashion, Newcastle made a forgettable start to life without Alan Pardew, who had been confirmed as Crystal Palace's new manager earlier in the day.
With Newcastle coaches John Carver and Steve Stone deputising in the dug-out, Leicester prevailed in the day's only all-Premier League tie courtesy of a 39th-minute header by Argentine striker Leonardo Ulloa.
Swansea City joined Leicester in the fourth round after a 6-2 romp at fourth-tier Tranmere Rovers.
Bafetimbi Gomis claimed a brace for Garry Monk's visitors, while Nathan Dyer, Tom Carroll, full debutant Mo Barrow and Wayne Routledge also found the net.
Blyth Spartans of the seventh-tier Northern Premier League looked poised to record the day's biggest upset after going 2-0 up at home to second-tier Birmingham City thanks to a double from captain Robbie Dale.
The scoreline even attracted the attention of former Portugal and Real Madrid great Luis Figo, who began to follow Blyth's official Twitter account via his @LuisFigo page.
But three goals in six minutes turned the tie on its head, with Lee Novak reducing the arrears in the 52nd minute before Wes Thomas claimed a quick-fire brace to give Birmingham a 3-2 win.
"I am exceptionally proud of the lads. We played some good stuff on a boggy pitch and we were very close to winning the game," said Blyth manager Tom Wade.
"We just hope that we can get more fans through the gates now."
The day's biggest upset came at third-division Rochdale, who beat two-time cup-winners Nottingham Forest of the Championship 1-0 thanks to a 12th-minute spot-kick by Peter Vincenti.
Meanwhile, Derby County, currently third in the Championship, needed an injury-time penalty by Chris Martin to see off fifth-tier Southport 1-0.
