Speaking on talkSPORT's Extra Time (via Ian Cruise), Marsh claimed to have sources close to the club who had informed him that Toure was unhappy at City.
People close to Manchester City tell me Yaya Toure is not very happy and he’s one of their great players.
When you start to hear rumblings from within the camp, and you see the way Toure played last weekend [at Sunderland], when he was strolling around and didn’t look interested, I’m wondering now if it will all go a little bit the other way.
It looks like they’re throwing billions of pounds at players but keep coming up short. I think this season could end in tears at Man City.
Who Marsh’s mole is remains anyone’s guess, but the spurious nature of his claims didn’t stop Toure from taking to Twitter to reject his comments.
Hey buddies, don't listen to the rumors, I'm happy at city..the Toure brothers are in Casa and are missing Manchester pic.twitter.com/ObNDjmMij4— yaya toure (@Toure_yaya42) November 13, 2013
But Marsh didn't give up there. He felt his sources were reliable, and he even had the nerve to suggest that Toure's response revealed a guilty conscience.
Same source as last year when I told you Mancini would be gone at the end of the season. You went apoplectic then too...— Rodney Marsh (@RodneyMarsh10) November 13, 2013
If there was not a fragment of truth in it why would YAYA come out immediately & deny it ..— Rodney Marsh (@RodneyMarsh10) November 13, 2013
Ask yourselves this. Why would YaYa dash to deny a rumour from an old man sitting in Starbucks in Florida?— Rodney Marsh (@RodneyMarsh10) November 13, 2013
But Yaya wasn't going to rest. He wanted to make clear to everyone Marsh's claims were nonsense.
@RodneyMarsh10 Out of respect for my fans and my club!! How can I be unhappy when i get so much love and respect from everyone in city?— yaya toure (@Toure_yaya42) November 13, 2013
To which, Marsh finally backed down.
Let it go people. @Toure_yaya42 told me I was wrong. Fair enough. Move on. Over.— Rodney Marsh (@RodneyMarsh10) November 13, 2013
But it wouldn't be Rodney Marsh just to leave it in a dignified way. Oh no. He then went on to suggest people should thank him if the row he started leads to a good run of form for City!
If yesterdays' little confrontation kick starts City's season, I want all of you fans to send me a 'thank you Rodney' tweet.— Rodney Marsh (@RodneyMarsh10) November 14, 2013
The idea that Toure, a player who signed a new four-year deal in April, would want to leave the club is just poor mischief-making from a man trying to remain relevant. Marsh cited Toure's lackluster display against Sunderland as evidence of his unhappiness, yet conveniently ignored the rest of his performances this season that have been superb.
Marsh has no links with the current inner circle at City, and any future comments he claims are from people "close to the club" should be treated with caution.
