Bayern Munich boss Hansi Flick has softened his stance on wanting new players in January as Robert Lewandowski and Serge Gnabry have returned to fitness.

Bundesliga top goalscorer Lewandowski had groin surgery following the 2-0 win over Wolfsburg in December and could not take part in the mid-season training trip to Doha.

Gnabry hurt his Achilles during the camp and only returned to full training this week ahead of the second half of the Bundesliga season.

Flick had stated publicly he wanted new signings to bolster Bayern's trophy push, comments that left sporting director Hasan Salihamidzic "surprised".

However, with Lewandowski and Gnabry ready to face Hertha Berlin on Sunday, Flick no longer appears desperate to bring in new faces in the transfer window.

"The injury situation has improved. Robert Lewandowski is back, so too Serge Gnabry, with a new haircut!" he told reporters on Friday.

"Robert is close to 100 per cent. He is an absolutely top professional and, when we were in Doha, he worked very well individually. Even when he was shooting, he didn't feel any pain.

"Lucas Hernandez will train on the pitch today. Javi [Martinez] and Kingsley [Coman] are a few weeks away. The goal is to have everyone together again in February and March, because then the tough weeks begin.

"It's true that I said [we need signings], but something has changed in the meantime. With the return of Serge and Robert, we've got two additions.

"I had a good conversation with Hasan and we both want to work successfully. When it comes to arrivals, it's important that players come to help us. I trust Hasan and his scouting department to make it possible for us.

"But that also has to be done carefully. You can't do anything crazy."

Bayern head to the capital in third place in the table, and they could be seven points adrift of leaders RB Leipzig by the time they kick off if Julian Nagelsmann's side beat Union Berlin on Saturday.

"We have to make a strong start. It's very important we start the second half of the season well," said Flick.

"We're all looking forward to it. We face a difficult task against a team that are very compact defensively. We must be prepared for that.

"We have the quality to become champions. Bayern showed last year under Niko [Kovac] that they can catch up. But we have to think from game to game.

"I don't feel any more pressure now than I did before the break. I really enjoy working with my team and coaching staff, but of course you're always under pressure, regardless of the situation."
