New signing Thorben Hoffmann will have benefited from a full week of training with Sunderland's centre-backs after being thrown in at the deep end last Saturday, according to Lee Johnson.
On-loan Bayern Munich goalkeeper Hoffmann made his Black Cats debut in the 2-1 win against Accrington Stanley last weekend, and at times his decision-making at set-pieces led to some heart-in-mouth moments when he came to collect aerial balls but got caught up in traffic.
However Johnson points out that the 22-year-old had only had half a day's training with centre-backs Tom Flanagan and Callum Doyle ahead of the game, with both defenders having been away on international duty with Northern Ireland, and England U19s respectively.

Sunderland head to Fleetwood Town this afternoon and if Hoffmann keep his place ahead of Lee Burge, he will have had more time to get to know the defenders around him, although it will be a different central defensive pairing in any case with Flanagan missing out through suspension and Bailey Wright expected to take his place.
In the immediate aftermath of the Accrington game, Johnson said that playing Hoffmann was a 'risky decision' but has now explained that that was because of the lack of time the new keeper had had to work with Flanagan and Doyle.
"The risk I was referring to was not so much blooding him [Hoffmann], but that the internationals had only come back on Friday," said Johnson.
"He'd had ten days training with everyone else, but not with the two centre-halves that were playing in front of him - he'd only had half a day to work with them and that's the bit that we've tried to work on this week as much as possible."
After the game, Johnson praised Hoffmann for making 'bold decisions', even if he 'maybe just hasn't quite got his timing yet'.
And Johnson says that, while goalkeepers will inevitably make mistakes, he wants them to be bold in order to set Sunderland off on the counterattack.
He said: "It's something we try to coach into all our goalkeepers - we want them to be bold.
"Our goalkeepers are going to make mistakes this year because all goalkeepers do, but it's the reaction to those mistakes that is very important, both their reaction as individuals and also the reactions of their teammates.
"We want them to set us off on a counter-attack, it's the way we want to play.
"There was one in particular last Saturday where Hoffmann had caught it, come out to the edge of his box with real tempo, but we had switched off when we could have had a one-vs-one in half the pitch - and they are good odds! - but we failed to take that chance.
"It's all part of getting to know each other, but bold goalkeeping is something we try to promote and encourage. Not silly or stupid goalkeeping, coming for things that you can't get anywhere near, but collecting things and then looking for very bold and direct counterattacking options."
Burge started the season as Sunderland's number one, but an elbow injury saw academy graduate Anthony Patterson take over in goal before the international break with the 21-year-old making his league debut in the home win against AFC Wimbledon.
Hoffman was one of two deadline day acquisitions, the other being winger Leon Dajaku who arrived on loan from Union Berlin, with that duo becoming Sunderland's eighth and ninth summer signings.
And Johnson is keen to give the German pair a chance to show what they can do, along with some of the other new arrivals, such as Niall Huggins, Frederik Alves, and Nathan Broadhead, who have had only minimal opportunities so far.
He said: "To be honest, over the next four or five weeks, I want to see what we've got because there are a lot of new players here
"We learnt a lot from the Blackpool [Carabao] game, blooding a lot of new players alongside a sprinkling of players who were here before and that have been consistent performers.
"It's early in the season but I think we can get results because we've signed players who we believe can get us there, but at the same time we need to know what we have got as quickly as possible.
"Ideally, we'd have done all this recruitment in pre-season and used those games to work out exactly what we've got, but as it is we are having to do that during the season."
