The two right-backs are likely to line up against each other in this weekend's huge Premier League clash at the Emirates.
The Gunners have been in very good form of late, winning their last eight games in the league, with that run seeing them climb to second in the Premier League table. Last weekend also saw them reach their second consecutive FA Cup Final - even if they did need extra-time to help them out in a 2-1 win over Reading.
Some may look at Chelsea's performances and suggest that they have been struggling to produce their best of late, but it's the results that count. They've won each of their last four league games and are unbeaten since the turn of the year.
The Blues could have the title wrapped up by the end of the week if they are victorious at the Emirates Stadium, and follow that up with a win over Leicester City.
But key members of both sides this weekend will be their right-backs. Mathieu Debuchy is likely to start for the home side after a period on the sidelines through injury, while Branislav Ivanovic has been a consistent performer for the Blues.
They may be just as important to their respective sides, but the two have reputations for different styles.

From the statistics here, you can see that Ivanovic is the more proficient when it comes to tackling but Debuchy seems to excel in other areas. Admittedly, the Arsenal full-back has played fewer games but his averages when it comes to ball recovery are impressive, he wins more duels per game and delivers slightly more crosses to highlight his attacking credentials.
When looking at the statistics, one may expect Chelsea to target Debuchy, with Eden Hazard likely to be up against him. The Frenchman, however, could be key to Arsenal going forward as Mourinho is likely to set his side up to be compact and ensure they're hard to break down.
