A decade spent at a singular club is supposed to yield with it a whole host of improvements to a player's footballing ability and importance to his team.
In the case of Arsenal and England forward Theo Walcott, this expected improvement has not occurred and as we enter the final games of the 2015/16 season, his role at the club has reduced to near minimal involvement.
Arsene Wenger now has a big decision to make in the summer months. Does he persevere with a project the club has invested masses of time in or finally ditch an asset who has descended into deadwood.

Here are four reasons why the sale of Walcott may now be the correct decision for Arsenal to make after ten years of service.
1. Emergence of Alex Iwobi and Joel Campbell
This season a predictable injury crisis at the club forced Wenger's hand, giving Costa Rican forward Campbell his first taste of Premier League football.

Since then, the winger has not looked back, with his work ethic, skill on the ball and eye for a key pass really impressing this season. Walcott himself has struggled to match the levels set by his new rival in the pecking order and has subsequently lost out on precious minutes this season.
Now another bright young forward has stolen the spotlight further condemning the Englishman to more time on the bench. Iwobi has started the last six league games for the club and during that time, he has reinvigorated what was a stale forward line and eclipsed Walcott's input.
The duo have a bright future at the club, their hungry attitude and drive are two attributes which the former Southampton man has really been lacking in the last couple of years which is why Wenger should dispose of the 26-year-old and instead focus on more promising players.
2. Ridiculous wages
With other players producing much more for the club this term, the concept of Walcott's ridiculous wages seems ever more ridiculous.
Arsenal utilise a very strict wage structure at the club, yet the Englishman commands one of the most prestigious amounts despite his poor performances.
The sale of Walcott would free up some cash in the Gunners' budget and perhaps bring a sense of fairness back to the structure in place.
With the majority of squad outperforming him a sale, for this wage issue, seems the most logical answer. After all, he's unlikely to take a pay cut is he.
3. Consistent inconsistency
Walcott's time at Arsenal has also become synonymous with the term 'inconsistent'. In fact, the term has come to symbolise his entire career and it has become even more apparent this season.
Typically, the Englishman has produced a few spectacular moments, with his sensational curling strike against Manchester City without doubt the most eye-catching.
However, he has been unable to establish himself as a consistent goal threat and has spent far too many games totally uninvolved in proceedings.
Arsenal simply cannot continue to employ a player who drifts in and out of games. One week he can be a match winner, the next a huge catalyst in a dismal display. No side with the ambition of the Gunners should tolerate this inconsistency and a sale again seems like the correct answer.
4. No settled position
A lot of this inconsistency can be attributed to Walcott not having a nailed down at the club. Is he a winger? A striker? No one seems to have a definitive answer and this is a huge problem.
How can a player produce the required form if he is constantly drifting between two different positions over the course of a seasons, two roles which require very different skill sets.
His lack of defensive contribution out on the flanks is a major issue, while his lack of ball retention and poor hold up play effectively rule him out as a long term solution to Arsenal's striker woes.
A player without a set position can prove to be a burden and this season it has become ever more prominent with Walcott. His service to the club has certainly not been all lows, but now the time feels right for he and the Gunners to go their separate ways.
