Sam Allardyce admits it was a risk signing Jan Kirchhoff after the defender endured a debut to forget in Sunderland’s 4-1 defeat at Tottenham.
The 25-year-old was signed from Bayern Munich during the week and came on at White Hart Lane with the scores level – but made several errors as Spurs came from behind to seal a 4-1 win.
Patrick van Aanholt had fired the Black Cats ahead only for Christian Eriksen to level for the hosts 91 seconds later and, with Sunderland on course for a point, Allardyce introduced Kirchhoff from the bench in place of Danny Graham.
Shortly afterwards Mousa Dembele arrowed in a second for Tottenham before Kirchhoff’s token attempt at blocking an Eriksen shot from distance saw the ball loop up off his leg and past debutant goalkeeper Jordan Pickford.
The defender’s abject afternoon was compounded when he tripped Danny Rose in the penalty area to allow Harry Kane to sweep home the resulting spot-kick and Allardyce admits the former Germany Under-21 international needs time to adapt.
“There wasn’t a lot he could do about the deflection,” Allardyce told BBC Sport.
“But the penalty, you don’t hang a leg out there unless you’re certain you’ll win the ball. Hopefully he’ll learn quickly.
“It’s a bit risky signing players from abroad in January but we have to take that risk. Hopefully he learns from today.
“Our legs were running out and I wanted to make sure we had the energy to stay in the game.
“John O’Shea and Wes Brown are in their late 30s so they will obviously feel the pace of the game. The extra defender was to tighten it up.”
Allardyce, whose side remain in the bottom three as they battle against the drop, also hit out at his players for conceding so soon after getting in front at White Hart Lane.
“Our players put themselves in one fantastic position and then in the space of a minute conceded. It’s one of the reasons we ended up losing,” he added.
“If we came in at half-time 1-0 up we could have built on that. It was a really sloppy thing to do. We ran out of legs in the end.
“In the last quarter you could see physically we were tiring. I changed the shape but that didn’t work.
“The scoreline, 4-1, looks more comfortable than it was. I’m disappointed we’ve lost 4-1. I could have accepted 2-1.”
