Why sending Yaya Sanogo on loan to Celtic would work for the SPL champions, and Arsenal.
The success of John Guidetti for Celtic could have a positive knock on effect for the SPL champions.
Manchester City's intention by sending the Swedish striker there was for him to get regular game time and start hitting form. He has done precisely that.
Guidetti has scored 10 goals in 12 games for the club, enhancing his reputation, unlike the unsuccessful loan spell he had at Stoke City last season.
It may prompt other leading Premier League clubs to look to Celtic, and vice versa, for the Parkhead side to try to repeat their success.
For all parties, another such move which could work would be for Arsenal to send Yaya Sanogo out on loan.
The French youth international is a player in who Arsene Wenger has great faith. Fans may argue too much, having started him ahead of Olivier Giroud in the Champions League against Bayern Munich last season; and his confidence has taken a dip with him still to score a competitive goal for the Gunners.
He is however clearly a talent. He scored four goals in one pre-season game against Benfica in pre-season, and netted twice for France's under-21s to help them beat England 3-2 last week.
With Olivier Giroud and Danny Welbeck ahead of him in the first team queue, and youngster Chuba Akpom also sitting in the wings, the Gunners could get by without him and a move would be beneficial for his development, and Arsenal will not be affected either.
Arsenal need to find out more about Sanogo, and a run of first team games isn't coming any time soon. Seeing if he is capable of emulating Guidetti's success is a good starting point.
