Premier League side Tottenham Hotspur announced a partnership with a United Kingdom paint supplier on Thursday, before the company appeared to mock Jose Mourinho's team on Twitter.
In a statement, Spurs said the Dulux mascot -- an Old English Sheepdog -- was given a tour of the club's stadium and training ground.

However, after Spurs posted a statement about the partnership on Twitter, the company took a number of shots at Mourinho's team.
"Can the dog play at centre-back?" one fan tweeted.
"He might do a better job Chris," the company tweeted back with a laughing emoji.
It's the perfect match - Dulux has become the first ever Official Paint Supplier to football giant Tottenham Hotspur!

Another fan asked about the possibility of getting the Tottenham trophy cabinet painted.
The company replied with a picture of a trophy cabinet with Spurs' logos photoshopped on and the caption: "For Sale, unused trophy cabinet."
The tweets were then deleted by Dulux, who later issued an apology.
"We're deeply sorry for the posts from Dulux this morning in response to the announcement of our relationship with @SpursOfficial," the post on Twitter read.
"These do not reflect how proud we are to be the Official Paint Supplier of the Club. We're investigating what happened and apologise to all Spurs fans."
Spurs jokingly replied to the tweet with: "We'll gloss over it this time."
They followed that up with another tweet of a photosopped image of a dog in a Tottenham shirt and a picture of Dulux deleting a tweet from October 2012 in which they declared their support for the north London side's arch rivals. It read: "I love arsenal forever and ever and ever."
Announcing the partnership, Spurs had said: "We are delighted to announce Dulux, the nation's number one paint brand, as our first ever Official Paint Supplier.
"The relationship will see us benefit from the unrivalled expertise in paint and colour that Dulux provides."
