Arsenal have started working with throw-in coach Thomas Gronnemark as the Premier League leaders look to increase their threat from set-pieces.
The Gunners have scored 14 goals from set-pieces in the top flight this season, more than any other side, but have yet to score from a chance created through a throw-in.
It is understood that Gronnemark will be working with the Gunners on a part-time basis.
The Dane previously worked under Jurgen Klopp at Liverpool between 2018 and 2023, and also did consultancy work at Brentford.
No Premier League team has scored more than the Bees (nine) from a throw-in situation since the start of last season, while Arsenal are one of only five to be without a single goal from throw-ins in that same period.
Declan Rice has become Arsenal's designated long-throw taker this season, with club's making ever-greater use of the opportunity to launch lengthy throws into the opposition's penalty area.
Last season, 20 goals were scored through throw-in routines, while 25 have already been scored during the current campaign.
"Throw-ins are underestimated by coaches, players, commentators and fans as something you should just do and see what happens," Gronnemark previously told BBC Sport.
During Gronnemark's time at Liverpool, the Reds' possession stats from throw-ins improved from 45.4% to 68.4%, moving them from 18th to first in the league on that metric.
He told BBC Sport in 2018: "If you are expecting professional footballers to be world-class throwers without coaching then you are pretty optimistic. Generally the standard is quite poor.
"A focus on throw-ins can save the life of small clubs, as a technique to survive.
"But at the top of the league, it can help with a more fluent style of play. No matter what position in the league, throw-ins are an advantage."
