The Sunderland boss has snapped up several new faces in January.
The transfer window is now shut and Sunderland have made plenty of moves to improve their current squad.
Sam Allardyce brought in the likes of Jan Kirchhoff, Dame N'Doye, Lamine Kone and Wahbi Khazri to strengthen their survival bid - as they look dangerously close to slipping away in the relegation fight.
The new signings are all exciting but January transfers so often do not work out, given the immediate need for success and the lack of a pre-season with new team-mates to settle into a squad of new players.
Speaking to Sky Sports News last week (28/01/2016) former Blackburn Rovers manager and Liverpool player Paul Ince spoke about the difficulties Big Sam will have with his new players - drawing on his own experience of heading to Inter Milan in 1995.
"It's always hard coming into a team in January, especially coming in from abroad. Having to settle in to what Sam wants and his ideas.
"It takes a while to settle in, for foreign players to settle in. I had the same when I went to Inter Milan it took me at least six months before I could settle in.
"It is tough, I remember the first day I went there. You're sitting at the dinner table your first day and everyone is speaking Italian and you kind of think they're speaking about you. It's a horrible feeling.
"But I am sure Sam has done his homework, done his research, and whatever players he brings in they have to have the mental toughness..."
Allardyce will hope not to have such a problem. German Kirchhoff already speaks some English and N'Doye previously played in England with Hull City - which will hopefully help him settle.
It is Kone and Khazri that represent the biggest problem on that front but they have French speaking lads to help them settle in the first-team.
If they can all adapt quickly on the pitch then Sunderland have a good chance of survival. But that adaptation will have to be rapid.
