With modern day football, there is usually a battle on social media long before the match actually takes place.
That’s been the case this afternoon as Barcelona and Manchester City have been arguing who has the better striker.
Barcelona posted a brilliant video of some sensational Lionel Messi free-kicks suggesting that “Messi loves big games like these!”
The clip shows the Argentine superstar scoring a number of brilliant set-pieces in some massive matches against the likes of Real Madrid and Atletico Madrid.
Manchester City’s reply?
Well, posting some of Aguero’s best goals.
The only problem is that his goals came against the likes of Stoke and Swansea - not exactly ‘big games’. Also, the goals didn’t quite compare of Messi’s incredible free-kicks.
And everyone was keen to point out their error, posting plenty of pictures and videos of Messi embarrassing City in the past - including him brilliantly nutmegging James Milner.
Take a look at the best responses below:
It was worth a try, though.
Of course, both Messi and Aguero will just want to do their talking on the pitch but they’re aren’t entering the game in the best form.
Messi has been sidelined for a number of weeks before his return this weekend’s 4-0 victory over Deportivo. We say he’s not in the best form but he did score just minutes after coming off the bench.
As far as Aguero is concerned, the striker must be struggling mentally after missing a crucial penalty for Argentina in the international break before failing from the spot against Everton this weekend.
That means he’s missed an incredible four penalties already this season and Everton boss Ronald Koeman admits that must be hard - even for a striker of Aguero's qualities.
"To miss two penalties, maybe it is a little bit of a mental question," said Koeman.
"Maybe for Aguero. I don't know, because it's not the first time that he's missed."
A Champions League clash against Barcelona at Camp Nou would be the perfect opportunity for Aguero to prove that he’s still one of the best strikers in world football - although even he would admit that he’s not quite at Messi’s standard despite his club’s Twitter account saying otherwise.
