Unai Emery has done some good business for Arsenal so far this transfer window.
The Spanish manager has wasted no time in adding to his squad since taking over as manager from Arsene Wenger.
Emery has already completed five signings: Lucas Torreira, Bernd Leno, Stephan Lichtsteiner, Sokratis Papastathopoulos and Matteo Guendouzi.
But with the transfer window set to close on Thursday, is Emery happy with his squad?
If reports are to be believed, it appears that the 46-year-old is still eager to add to his options.
The Sun report that Emery is 'not impressed' with the defence that he has inherited from Wenger: with the centre-back position said to be a huge worry.
He is not convinced by Mustafi, Calum Chambers and Rob Holding, while he does not believe Konstantinos Mavropanos is ready for regular Premier League football.
So what does he plan to do about it?
Emery has already shipped out Chambers on loan to Fulham, and he is now intending to strengthen the position by plotting a move for Domagoj Vida.
The Croatian centre-back was a vital cog in his country's run to the World Cup final in Russia.
But Arsenal are struggling to raise the £25 million needed to sign Vida, and need to offload either Shkodran Mustafi or Danny Welbeck before the transfer window closes to complete a deal for the Croatian.
It has already been a busy transfer window for Arsenal, but it seems there still could be a few deals yet at the Emirates.
Arsenal fans will be hoping that Emery can bring success to north London in his debut season at the club.
And Pep Guardiola has given an insight as to how he operates as a manager.
"Unai is a work-ethic guy," Man City boss Guardiola said on the Sky Sports Premier League Launch Show, per the Express.
"He knows absolutely everything for the opponents. He achieved something unique in European football, three Europa Leagues in a row.
"He handles so good in PSG, was unlucky with 4-0 and Barcelona and that I think is when he marked his spirit a little bit in PSG, but he made a good job.
"He's a top, top manager, it will be tough. It's a good challenge for all the managers and for me to challenge him here in England will be a good challenge for me."
