Romelu Lukaku has taken to Twitter to question Mesut Ozil's transfer from Real Madrid to Arsenal.
As reported by Goal.com, the Belgian forward took a dig at the German international by claiming that he doesn't understand why Ozil left the Bernabeu.
Ozil, of course, completed his move to the Emirates in last summer's transfer window for a fee of £42.5 million. However, the German playmaker struggled to find consistency in his debut season in north London, and has also failed to make a major impact in Brazil, despite being part of a team that has reached the World Cup final.
In fact, before Germany's semi-final clash with Brazil, many insisted that the playmaker should have been dropped for the clash. And, even though his national side demolished the Brazilian's 7-1 in their own back-yard last night, Ozil struggled to make a major impact on the game.
And now Chelsea forward Lukaku has had his say on the 25-year-old. The Blues ace tweeted: "No disrespect to Arsenal who is also a big club but i don't understand why ozil has left real madrid.... I guess will never know.."
Lukaku, meanwhile, may have to start thinking about his own career, with his long term future at Chelsea still seemingly unclear. The striker - who was part of the Belgian set up beaten in the World Cup quarter-final - has spent his last two campaigns on loan away from Stamford Bridge, and could yet move on in this transfer window.
It remains to be seen as to whether Lukaku makes a switch, but he would certainly prove a major coup for potential buyers as he's a proven Premier League scorer.
What next for Ozil?
Ozil, on the other hand, will be desperate to prove his critics wrong in 2014/15. His immediate attention will be on Sunday's World Cup final, but he will be targeting success at the Emirates next term.
The Gunners ace certainly has the quality to turn his career around in north London, but must start producing consistent levels of performances on a regular basis. Going into the new season with a possible World Cup winners medal won't be a bad start, but he must deliver as Arsene Wenger and Co. target the Premier League title next season.
The Gunners will be looking to build upon their FA Cup success from 2013/14 and will hope momentum plays apart as they target more silverware.
