Any team going up against Manchester City this season will naturally have their minds drawn to the prospect of facing Erling Haaland and, more importantly, trying to figure out a way to stop him scoring.
It is a feat which few have achieved so far since he arrived from in the summer - only AFC Bournemouth, Liverpool, and his former side Borussia Dortmund have managed it in the 16 games he has played in all competitions
Brentford will be looking to become the fourth team on that elusive list, and while their manager Thomas Frank has admitted that doing so will be very difficult, he has identified a potential route for nullifying his threat.
"He [Haaland] is a goal machine that will break records going forward," Frank said. "He's already done that so far and he'll continue doing it.
"He's playing for a team that is giving him probably the best possibilities to score goals; they will provide him with good opportunities from crosses or slide passes.
"It's about trying to stop the source; the more we can stop the source, the better. It will not be the first time that people have tried to keep [Kevin] De Bruyne quiet; he always seems to find a way."
Confidence from previous meetings
These two clubs last met back in February at the Etihad Stadium, when it took a Riyad Mahrez penalty and a mistake by David Raya for the hosts to overcome an otherwise strong Bees' backline.
It was a similar story in the return fixture too - when City travelled to west London between Christmas and New Year, they were forced to work hard for the 1-0 win they eventually picked up courtesy of Phil Foden's strike.
Based on the showings from his side in those games, Thomas Frank rightly feels as though he can be a little more optimistic at his side's chances of getting something from what is undoubtedly a very tough game.
"We showed a few bits to the boys about the last two games against them [Man City] and also a couple of other games because City and Pep [Guardiola] always find new solutions that you need to be aware of," the 49-year-old Dane revealed.
"We managed to keep them not quiet but relatively low on shots and expected goals if you take away the penalty in the second game. In that aspect there is some confidence, but you are never satisfied just losing 1-0 or 2-0 - you always want to go for the win.
"That will be the same. At the end of the game, we'll see if it was a good performance or not."
A positive mentality
In the end, the challenge of playing Man City is one which almost no coach in the world would be able to say is an easy one to solve - after all, it is not luck that they have won the Premier League title in four of the last five seasons.
They may not sit top of the table for now, but they remain very much in the fight and have still lost just one game domestically so far, and they are the league's top scorers too with 39 goals - an average of three per game.
All of that combines to create a daunting task ahead of Brentford, something Frank summed up when he asked, "Is it going to be difficult? It'll be unbelievably difficult.
"They have an almost complete squad and added Haaland who will be destroying goal records in the coming years. They are an unbelievably difficult side to close down, but I back us to do something.
"We have never, ever gone into a game believing that we're not capable of winning. It's most likely the biggest challenge and we're looking forward to it."
