Sergio Aguero
For a player like Sergio Aguero, a move from Manchester City to Arsenal would be a double-edged sword. While it would give him the chance to continue his career in England, it would resemble a fall from grace at a club where he scored arguably their most important goal in history.
But Aguero knows the existing status quo at the club. He is no longer first-choice and Guardiola’s reluctance to play the highly-mobile Gabriel Jesus instead of a pure no.9 proves that the Argentine striker may not be in the starting lineup much longer.
This is a World Cup year and Aguero needs all the game time he can get if he is to start for Argentina as well – a team that has stiff competition with the likes of Juventus' Gonzalo Higuain and Inter Milan's Mauro Icardi.
The only stumbling block is the lack of Champions League. Can Aguero trust Wenger to lead Arsenal back to the Champions League in one season? The Premier League will only get tougher while the Europa League campaign is long and arduous – highly improbable without squad depth in each position.
City are also in the same boat as Arsenal – they would not want to strengthen a domestic rival. But if Aguero is keen on the move, Arsenal would be worth a risk unless a bigger club comes in with a higher bid and can offer him Champions League (a competition Aguero has stated he wants to win before possibly finishing his career back in Argentina).
