Arsenal have been drawn to face Turkish club Fenerbahce in the Champions League play-offs and on paper it looks like a tough draw.
English clubs have experienced in the past just how intimidating it can be to play in Istanbul, and from a footballing stand point Fenerbahce are a handy team too.
They finished second in the Turkish League last season, won the Turkish Cup and reached the semi-finals of the Europa League by beating the likes of Borussia Monchengladbach, Marseille and Lazio along the way.
Brazilian midfielder Christian Baroni adds a creative spark in midfield, Senegal striker Moussa Sow was their main goal threat last season, and he has been complemented by the re-signing of ex-player Emmanuel Emenike who has joined from Spartak Moscow for €13m.
The real player to watch though could be young midfielder Salih Uçan - he is considered one of the brightest Turkish talents of recent years and has been linked with Manchester United.
So it's far to say that Arsenal - who are still without a big name signing this summer - could be in trouble on the pitch.
Off the pitch, however, it could be a different matter, since Fenerbahce's match fixing shenanigans could well see them thrown out of the tournament if they beat the Gunners.
Fenerbahce are awaiting a final ruling from the Court of Arbitration for Sport over whether they will be allowed to go into the competition proper this season, having been banned from competing in Europe by UEFA for match-fixing in domestic competition.
They have challenged that ruling and a CAS verdict is due before the group stage draw is made, but home and away matches against Arsenal stand to go ahead before that decision arrives.
UEFA on Friday said no decision has yet been made regarding what would happen in the event of Fenerbahce winning the tie and losing their CAS appeal, and there is no specific precedent that we can draw on.
However, UEFA's usual policy in similar situations is to allow the most recently beaten team to qualify if a side has been thrown out of one of their competitions for whatever reason.
Celtic benefited from this in 2011 when they were parachuted into the Europa League group stage despite losing 3-1 on aggregate to Sion.
Sion were kicked out for fielding players in the tie that they'd signed while under a transfer ban.
In 2007, Partizan Belgrade beat Bosnian side Mostar 6-1 in the first leg of their UEFA Cup tie but were expelled due to crowd trouble by their fans. The Serbian club were allowed to play the return leg while their appeal was being processed, which they won 5-0, but their appeal was then rejected and Mostar were allowed to progress to the next round.
The one reason why it might not be such clear sailing for Arsenal is that Fenerbahce have already played in the Champions League this season.
They defeated Red Bull Salzburg 4-2 in the third qualifying round and the Austrian club could protest if Fenerbahce are eventually kicked out.
Salzberg are actually owned by the energy drinks company so there is no doubt they have some deep pockets and some top lawyers on the payroll who will look to exploit the situation.
However, with the draw for the Champions League due the day after the CAS ruling it is likely that UEFA would have no option but to put Arsenal in the group stage if Fenerbahce were kicked out. They'd then have to deal with Salzberg's issues in court as even if Arsenal win the tie, Fenerbahce's previous participation will remain an issue for them.
For now though, there is nothing Arsenal can do but play the match.
"We put the politics aside and Arsenal will concentrate on the football side," Arsenal official David Miles told The Associated Press after the draw. "We will keep in touch with UEFA."
Which is all well and good, of course, but it's nice to know that there may just be a lifeline there if they need it.
