Dundee are in negotiations to keep both their German trialists at Dens.
The Dark Blues are keen to get both Luka Tankulic and Thomas Konrad signed up to permanent deals, ahead of their return to their homeland this week.
Manager Paul Hartley admitted last week he was impressed by the duo.
And that was underlined on Sunday when former Borrusia Dortmund kid Tankulic scored the second goal against English champions Manchester City and Konrad put in a Man of the Match showing.
Gary Harkins, now in his third spell at Dens Park, opened the scoring for the Dark Blues.
Regarding the two Germans, former Scotland international Paul said: “We are speaking to them but they have a couple of other options open to them.
“They’re young, look hungry and want to do well.
“They did really well. Luka did well up front because it’s difficult to play as a lone striker he held it in well.
“And Thomas was strong and commanding at the back too he worked well with Jazza (James McPake).
“The two German lads have been with us for the last week or so and we will see what happens with them. We just wanted to see them in a game.”
Meanwhile, the manager has confirmed, Scott Bain, who was struck down with appendicitis last week while in Hungary, could be back in training in just three weeks.
The keeper flew back from Budapest on Saturday, with coach Bobby Geddes, after being given the all clear by medics in Central Europe following his operation last Thursday.
“Scott is back,” said Paul.
“We’re looking at two or three weeks on the sidelines.
“It was keyhole surgery so that should make the recovery much easier.
“He did well in pre-season so it’s a shame he will have to miss out.”
On the Manchester City match itself, Paul was over the moon with the performance of his players in beating the Citizens.
He said: “I was pleased, it was a good workout for our first game. We had a good shape about us.
“The fitness and the energy levels were good, especially against a top, top team.
“It’s not every day we play against opponents of that standard so the players did well. They were not overawed and played some good stuff at times. We’ve just got to keep progressing.”
Dundee are away to Brechin City on Wednesday.
