I can't see this as anything more than a simple foul at the Premier League level unless the game in general is bordering on becoming out of control. A word with the attacker would be good after calling the foul, but it's just not a card in my opinion. I had the game on in the background, but I didn't think the temperature of the game was that bad where something like this was after the buildup of other issues.
In my games, I do think the temperature of the game would help me determine whether I issue a caution or not. In a game without much else going on, I'm probably going to loudly admonish the attacker to watch himself so the keeper and defenders know I saw what happened. I'd also probably give an "advantage" to allow the keeper to distribute the ball as he/she wants (of course, assuming the keeper isn't injured like Leno was here and the keeper doesn't lose control of the ball). In a chippier game, I'm going yellow on this. At best, this is a "buzz the tower" type of play that is sending a message to the keeper. You want the players to know you aren't going to allow such antics to go unnoticed.
I'm not always the biggest fan of taking the temperature of the game into consideration for whether I issue a card, but this is one of those times.
