On February 11, Craig Delew, a 19-year-old fan of League One side Leyton Orient, tweeted at the club's chief executive vowing to clean every seat in Matchroom Stadium's East Stand if they brought back goalkeeper Eldin Jakupovic.
The Bosnian keeper had been recalled by parent club Hull City at the end of January after a brief but successful loan spell that only lasted a few weeks.
Orient chief executive Matt Porter saw Delew's tweet and decided to "keep that one in the memory bank."
"Like all good clubs, we decide our transfer policy based on what our fans tweet," joked Porter, who is surely in for a constant stream of Lionel Messi requests from now on.
And when Jakupovic returned to Orient on a loan until the end of the season just two days later, Porter called on Delew to fulfil his promise.
Since the club came through for Delew, he came through for the club. And on a cold February day, he cleaned the East Stand's 3,636 seats.
In recognition of Delew keeping his word and putting in the manual labour, the club then arranged for him to watch their match against Stevenage from the director's box and meet the player he requested afterwards.
Jakupovic gave Delew his gloves from the match, in which he kept a clean sheet as Orient won 2-0.
Delew later reported that they were quite smelly.
Orient currently sit atop League One after following up their success against Stevenage with another 2-0 victory against Swindon Town, giving Jakupovic two clean sheets in a row.
