The Premier League transfer window has officially opened.

One team that will be looking to strengthen this summer is Arsenal.

The north London club have had a promising season.

They managed to close the gap on the top four and finished fifth, just one point behind the Champions League spots.

Arsenal could yet still qualify for next season's Champions League by beating Chelsea in the Europa League final.

But even if they do beat Chelsea they have showed they have a lot to improve and will be looking to strengthen in the coming months.

So, what exactly will they do?

David Ornstein of the BBC has outlined Arsenal's plan for the summer at this current time.

He starts by outlining the difference in budget Arsenal will have depending on their qualification for the Champions League.

"It won't be the most spectacular window, but the Gunners do have some very important business to conduct," he starts. "The key question is the size of their budget.

"With Europa League football, we're told it will be as low as around £40m. But with Champions League football, it will be higher. I've been led to believe that could mean up to £100m."

Their priorities this summer will be signing a centre-defender and a central midfielder to replace Aaron Ramsey.

"Despite the continued absence of a technical director, the existing recruitment team have identified targets and conversations are under way," he continues. "They're looking for experience and youth.

"Their priorities are a central defender and box-to-box midfielder.

"Jeremy Wilson from The Telegraph mentioned Getafe centre-back Djene Dakonam, who is under contract until 2021 and has a 35m euros release clause.

"The midfielder will replace the outgoing Aaron Ramsey.

"Arsenal came close to a deal for PSG midfielder Christopher Nkunku in January, while Adrien Rabiot is another they've pursued in the past - but I've not heard that either are targets this time round."

And they also want to sign a winger, forward and full-back.

"Another position they would like to fill is a wide forward. In the last window, they tried to sign Inter Milan's Ivan Perisic and were also talking to Yannick Carrasco of Dalian Yifang. I doubt that interest will be reignited.

"Other areas in which they will try to add depth are up front - Danny Welbeck is leaving and there is a desire to send Eddie Nketiah on loan - and at full-back."

And Ornstein also reveals PSG interest in Pierre-Emerick Aubameyang but the club will not entertain any offers.

"We mentioned Thomas Tuchal's admiration of Roberto Firmino - he is also keen on Pierre-Emerick Aubameyang," he concludes. "But like Liverpool, Arsenal would rebuff any advances."
