Some may have thought Costa was lucky to stay on the field in the League Cup final.
The Blues forward played an integral part in their second goal of the game as his cross was deflected in off Kyle Walker to secure Jose Mourinho's third League Cup - his first trophy since returning to the club.
Bentaleb told the London Evening Standard: "Was he lucky not to be given a card? Maybe. I don't know what was happening in his head, but I stayed focused on my game.
"Sometimes you have arguments with players. It's nothing bad. This kind of thing happens every weekend."
Costa's conduct is always seemingly under the spotlight given his fiery nature, and his seeming desire to confront opponents throughout the game to fire him up is a major talking point.
In yesterday's encounter he seemed to push Bentaleb in the face, though what saved him was that he wasn't really looking at his opponent, and it could be construed that he was trying to shield the ball.
It wouldn't be the first time Costa has been involved in an incident like this, given that he was banned for stamping on Liverpool's Emre Can in the second leg of the semi-final in the same competition at Stamford Bridge.
Spurs need to put the disappointment of their cup final defeat behind them as they will try to breathe fresh life into their challenge for a Champions League place against Swansea at White Hart Lane on Wednesday.
He added: "We have to take the disappointment in the right way. Now we have to put some smiles back on our faces and on our fans' faces and Wednesday is a good chance to do it."
