Joey Barton has denied allegations that he assaulted Barnsley boss Daniel Stendel in a tunnel incident.
His team Fleetwood Town were controversially defeated at Barnsley last Saturday in their League One clash.
Following the game, Barnsley confirmed an incident took place in the tunnel amid claims Barton confronted Stendel.
But now, the Huyton-born former football player has declared his innocence on Twitter.
In a statement he wrote: "With regards to the alleged incident on Saturday following our game against Barnsley, I emphatically deny all the allegations made.
"Given this matter has not been formally closed, it would be inappropriate for me to make any further comment."
South Yorkshire Police confirmed that a man has been arrested on suspicion of a racially aggravated public order offence and racially aggravated assault.

He has been released on bail.
They said: "Officers investigating the incident would be keen to speak to anyone who may have caught the incident on camera or who may have mobile phone footage immediately before or after the incident occurred.
"We would ask members of the media and the public to refrain from speculation in relation to this incident, as it could potentially harm the investigation."

Officers earlier appealed for witnesses to the incident, which Barnsley player Cauley Woodrow claimed left Stendel with "blood pouring from his face".
Barnsley announced on Tuesday that they had lodged formal complaints with both the English Football League and the Football Association over the alleged incident after the match, which ended in a 4-2 victory for the home team and saw Fleetwood have a player sent off after 65 minutes.
