Leeds United have a squad that is good enough to earn Premier League promotion, but it would be naive to ignore the potential hurdles that could crop up.

Daniel Farke knows this, which is why is 'staying awake' to possible additions before deadline day. He has confessed that there is no direct back-up to Brenden Aaronson while Patrick Bamford’s injury problems mean the striker role is also another area he is watching.

However, Farke has also underlined that it is hard to improve a team that is top of the league. The basis for that theory was clear to see in Saturday’s 7-0 mauling of Cardiff City. Six different scorers, a fifth straight clean sheet - with Pascal Struijk now back - and Leeds now unbeaten in 13 matches across all competitions.

Farke is seeing his transfer stance being justified. The manager has frequently reiterated his January criteria of only wanting recruits who are of good character, of top quality and are affordable.

That is because the options already at his disposal are playing at such a high level in this Championship season. Of course, it is clear that absences to Joel Piroe and Brenden Aaronson - who scored three goals between them against Cardiff - could land Leeds in a bit of a hole.

And after the rout of Cardiff on Saturday, Farke refused to rule out any incomings. Asked about whether the game has changed his transfer stance, Farke said: “You can't be driven too much by your emotions.

"[Either] after a loss and you feel you have to panic - or after a great day like this to think the next games will all be that easy and you win easily 7-0.

"We spoke quite openly about [how] I totally trust this group and if we go with this group, I'm confident that we can finish in a top position.

“But I think also it's our responsibility as key people in the club to explore if there is something that could improve the group a bit and make the probability higher that we are successful in the end.

“To find something where we think, okay, it's a good addition that's affordable, we will go for it, and if not, then not. So we are not over the moon after this win. Even if it would be a 0-0 stalemate today.

“So our general picture won't change. But it was again proof that we have a good group and we can be successful also with what we've got.”

In his press conference, Farke exuded a figure who was, of course, very pleased with the win but was not getting carried away with the result.

It reflects his tone for the whole window - showing a sensible balance of placing confidence in his squad while reminding them that there is always room for improvement.

That message of trust has seen his squad repay him so far and the coach's mantra is rubbing off on the players too. “We believe in the squad and the players we have,” said Aaronson, Saturday’s first goalscorer, in the tunnel after full-time.

“It’s not up to me or the other players. But if they bring in anybody, we will bring them in with open arms like we always do, and keep going like this.”

The players and manager are all on the same page, which is unsurprising given the form of the team but nevertheless essential when going for promotion. It’s all working together of their good.

Leeds are top of the league with 18 wins out of 30 league matches, with a plus-41 goal difference and an unbeaten streak of 12 league games. Perhaps it's best not to disrupt the apple cart unless something undeniably tasty emerges.
