Barcelona's eventful summer transfer window of 2017 came to an anti-climatic end as the club failed to secure a signing on deadline day. With Neymar's move to PSG crippling the club in a footballing sense, Barca were left scrambling as they grossly overpaid for Ousmane Dembele to replace the Brazilian.Failed moves for Marco Verratti, Inigo Martinez, Jean-Michael Seri and Philippe Coutinho coupled with the contractual uncertainty over Lionel Messi led to calls for club President Josep-Maria Bartomeu to resign, with a no-confidence motion currently underway. The club held a press conference to explain their transfer dealings, but that only served in more scorn and outrage on social media.Here's how Twitter reacted:Barcelona report they didn't sign Coutinho because Liverpool wanted £183m.Just imagine how much this man would cost in today's market. ? pic.twitter.com/NNI9Arm0oB— bet365 (@bet365) September 2, 2017Barcelona claim Liverpool wanted €200m (£183m) for Philippe Coutinho, and that's why the deal didn't happen. pic.twitter.com/lX6woKD9Ur— Paddy Power (@paddypower) September 2, 2017The only way Barcelona can win trophies this season in a single photograph. pic.twitter.com/IC2z4ZheuZ— Rafael Hernández (@RafaelH117) September 2, 2017Barcelona, the only club in the world where humiliation in the transfer window ends with a conference of blaming everything by themselves.— Rafael Hernández (@RafaelH117) September 2, 2017Admirable that Barcelona open themselves up to questioning like that. But they pretty much failed to answer a single question adequately.— Sid Lowe (@sidlowe) September 2, 2017According to Barcelona, Liverpool were willing to sell Coutinho for €200m on deadline day. pic.twitter.com/IK5AN6DbKu— LFC Fans Corner (@LFCFansCorner) September 2, 2017Liverpool offered Coutinho to Barcelona for €200m, Barcelona have announced.
