Arsenal was left unsatisfied at the end of January's transfer window when they couldn't add Denis Suarez from Barcelona.
Unai Emery has admitted that the club was looking for possible three players during the window, but he had to reckon with one after moving to Ivan Perisic, and Yannick Carrasco proved to be unsuccessful.
This did not help Arsenal, due to lack of funds, to buy the loan market, but this season there will be funds available for Emery to strengthen its team, and the Spaniards are well aware that much remains to be done to get Arsenal back to the best in Europe.
So what could be the summer shopping list in the Emirates? We look.
The French midfielder was close to joining in January, but talks between Arsenal and Paris Saint Germain finally stopped.
In recent years, Arsenal has been carefully watching Nkunk, and the club is interested in the arrival of Unai Emery in the Emirates.
Arsen Vener was a big 21-year-old admirer and Arsenal's main French scout, Ty Gooden, has accumulated extensive knowledge of the midfielder.
In any case, Nkunku was always looking for a summer destination, but Arsenal tried to speed up the move in January when it became clear that he might be available.
So it would be no surprise that Gunner will review his interests at the end of the season, when Nkunku will be just one year out of his deal with French champions.
Arsenals, of course, this summer, after seeing that their move to Perisik and Carrasko will fail, will bring horror.
Pepe is highly valued in the Emirates, and Sven Mislintat has identified him as a player who could win the Premier League.
In January, Lille's attacker moves to China, supporting her stay in France and trying to help Lille qualify for the Champions League.
But in the summer he will be very interested in some of the best clubs in Europe, and Arsenal hopes it will be in a combination.
Another player who has been on the radar for some time at Arsenal.
Soccer manager Raul Sanllehi is a big leader of Boca Juniors, and in the past there has been a discussion between the two clubs about a possible deal.
In January, there was no chance of Arsenal's financial situation, but with the cash that was available in the summer, Arsenal would finally be able to move to Argentina.
Arsenals could be in the new holder's market in January thanks to Petr Cech's retirement.
Emiliano Martinez, who is currently reading a loan, says that he has been told that the club plans to choose him again when he returns in the summer.
If it is, and Martinez remains in the north of London, a new third-choice holder can come.
Dean Ilyev is already in the club club, but 19-year-old Polish manager Radoslav Majecki, currently based in Warsaw, has a strong intention.
Arsenals scouts have been admired by adolescents for many years in recent years and this summer is an opportunity.
The Celtic left spine has been the long-term goal of Arsenal, which has seen a 21-year-old return.
Tierney even refused to move to the Emirates two years ago to stay in Scotland because he thought it would be the best in this career.
Several major clubs in England hold tabs on the left, including Manchester United, and it could be summer when he decides to move on to the Premier League.
Finding the New Left is Arsenal's priority this summer. Leicester's Ben Chilwell is also very fond of North London, but it might be that he is now considered too expensive to be forced on the England team.
Unai Emery is a major Côte d'Ivoire international fan who has found difficulty in England since joining Manchester United two years ago.
Arsenal had a preliminary loan approach, which was killed by the UK in Baillia in January, but in the summer it was able to check the waters with a firm offer back to the center.
At the end of the season, Bailly will only be one year old in Old Trafford, but United will be able to extend the deal for another 12 months.
