Conor Chaplin and the other Portsmouth deals which came under the spotlight
Loan players are a talking point ahead of next Tuesday's trip to Coventry.
That's with the debate over Conor Chaplin's participation in the game at the Ricoh Arena aÂ focus.
Pompey can make the call over whether the striker features, as part of the loan agreement which becomes a permanent deal in January.
It's not the first time such dealsÂ have been under the spotlight, of course.
The most famous incident came after Lomana Lualua's inclusion against parent club Newcastle, after joining Pompey on loan in 2004.
There was nothing in the termsÂ which prevented him appearing against the Magpies, and the DR Congo man went on to score in the 89th minute and help Harry Redknapp's side to a 1-1 draw at Fratton Park.
As a consequence of that, aÂ change was invoked in the Premier League which stopped such a scenario developing.
Such a rule doesn't exist in the Football League or, indeed, Uefa, with Thibaut Courtois playing against his parent club Chelsea for Atletico Madrid in the Champions League semi-finals in 2014.
Although not a loan, Rommy Boco's appearance for Accrington against Pompey came in for attention in 2016.
Boss Paul Cook was fuming opposite number John Coleman played the Benin international after he agreed to cancel the final six months of his contract at Fratton Park and allowed him to move to the Crown Ground.
A gentleman's agreement between the managers was put in place saying the midfielder wouldn't feature when theÂ two sides faced each other.
And that was the case with both Nigel Atangana's move to Leyton Orient and James Dunne's switch to Cambridge in the same 2015-16 season, with both clubs abiding by the request.
Boco was named on the Accrington bench, however, leading to a furious bust-up between the managers, who wereÂ friends, after the team-sheets went in.
Cook was livid with the move, leading to breakdown in the relationship with the man who managed him at Stanley at the end of his career.
Boco was introduced as a 67th-minute substitute as Pompey cruised to an impressive 3-1 win on the night.
