With just over a week left of Euro 2016, club managers will be putting their final plans together for the season ahead.
Jose Mourinho has the important task of deciding which players from the past two lacklustre campaigns under Louis van Gaal he wishes to retain for the 2016-2017 season.
During his time at Manchester United, Van Gaal made 15 signings, including the seemingly pointless loan of Andy Kellet from Bolton Wanderers, and the signing of promising youngster Regan Poole.

Radamel Falcao and Angel Di Maria have already been shipped out of the club, with the Dutchman unable to get the best out of either player. Di Maria made a promising start in the Premier League, but problems on and off the field contributed to his downfall and eventual transfer away from England.
Victor Valdes had a bust-up with the former United boss and was subsequently sent out on loan to Standard Liege, eventually leaving United when his 18-month contract expired.
That leaves 11 players still under contract at United who were signed by Van Gaal.
It is clear to see by their performances that Anthony Martial and Luke Shaw have huge futures at the club.
Before the horrific leg injury sustained against PSV Eindhoven, Shaw was arguably United's best player, and it really was a blow to lose him for the rest of the season, when he was starting to show the kind of form which he consistently showed at Southampton.
Martial signed for United surrounded in controversy due to the fee paid for him, which could rise to £58 million. However, Martial immediately started paying back his huge fee when he scored off the bench against Liverpool and scored two on his home debut against Southampton.
It is clear that Mourinho will value these two young players.
Sergio Romero, Bastian Schweinsteiger, and Morgan Schneiderlin all had steady, but not spectacular seasons, and it is fair to assume that they will be fighting it out for squad places again.
Schneiderlin has the potential to be the bite that United's midfield has dearly lacked since the Roy Keane days, but needs to improve his distribution which is often lacking.
It is evident that Schweinsteiger is not the player he once was, although can still play a big role when games need to be managed with the calm and steady passing he brings to the team.
Herrera quickly gained a rapport with the fans due to his forward thinking play, however, this has been seen less and less over the last season, with him often choosing the safe option over the potential killer pass or dribble.
Herrera possesses enough technical quality to succeed at a big club, although the seemingly imminent signing of Henrikh Mkhitaryan may mean he has to settle for a lot less playing time.
It may be worth watching the outcome of Memphis Depay over the next few months. The class and form which he showed in the Dutch Eredivisie is undoubted. Although after a bright start in both Champions League qualifiers against Club Brugge, there were not too many other games in which he showed any of these talents.
He played the second half of the season seemingly constrained and with little, to zero, self-confidence.
Mourinho has been heralded as a manager who can motivate his players and instill confidence, and this will be needed if Depay gets a second chance at Old Trafford. He possesses all the qualities needed to strive amongst the elite, but can Mourinho get the best out of him in the Premier League like he managed to with Eden Hazard?
The final three players are the most likely of Van Gaal's signings to leave the club.
Marcus Rojo, Matteo Darmian, and Daley Blind all played a large number of games in the 2015/16 season, and all of them had up-and-down seasons.
Firstly, Rojo, the player recently sent off for a reckless and pointless challenge in the Copa America final, had a very inconsistent season.
Whether it was left-back or centre-back, he was constantly caught out of position, and when he did manage to make a tackle, it ended in a weeks injury due to the amounts of injuries he sustained.
Rojo should be the first player up for sale and should not make the squad next year.
Darmian was as injury prone as Rojo but usually fared better in defense, even when being played out of position at left-back.
The first half of the season looked as though United's right-back woes may be solved, until the niggling injuries and poor performances crept in, and since then, he has seemed somewhat unsettled, which has generated a large amount of speculation in a return Italy with Juventus.
Daley Blind was used at centre-back the entire season and there were many times in which you could tell he simply was not good enough for the position.
Blind could be kept as a squad player as he is adept enough to be good cover at left-back and can slot in midfield when United need to wind a game down, but his form over the last couple of seasons suggests he is not good enough for United's starting 11.
Out of all the players which Van Gaal brought in, there are only two players which can be seen as must-start players in the season ahead, and out of £250 million spent, that is simply not good enough.
