Crystal Palace midfielder Jason Puncheon could face legal action from Neil Warnock after he reacted in a series of tweets to his former manager's criticism of his penalty miss at Tottenham, while the FA said it is looking into the situation.

Puncheon -- whom Warnock signed on loan when manager of QPR in September 2011 -- spurned the chance to give struggling Palace an early lead at White Hart Lane when he blasted his spot-kick horribly high and wide. Spurs went on to win the match 2-0 as the Eagles were left bottom of the Premier League.
Puncheon, 27, came in for criticism from many commentators over the weekend, but took exception to remarks from Warnock in his role as a pundit on talkSPORT and made accusations about the manager on Twitter.
Puncheon, on loan at Palace from Southampton, has since deleted his posts. An FA spokesman said: "We are looking into it."
Warnock, sacked by Rangers in November 2012, revealed that he had been alerted to the matter and was considering his next course of action.
“He's made comments that I know nothing about, and if it's been suggested that I've done anything untoward then I can confirm that I most certainly have not,” Warnock told the Daily Telegraph. “The matter is being addressed with him directly now on my behalf.”
Puncheon left only the following post on his official Twitter account.
One earlier tweet had read: “Everything else is banter and opinions and as a man I will live with that which is fine but I will not live with his opinion.”
Warnock had not held back in his criticism of Puncheon during his comments on live radio.
“There's no way I would've trusted him with a penalty. You've got to have somebody a little bit more cool, and he's not like that, Jason,” he said.
“He can whack a 35-yard free kick in here and there but a penalty, with all the pressure on him at a place like White Hart Lane -- not in a million years for me.”
Warnock added: “I think a centre-half might have done a bit better! Obviously, he never meant to put it up there.”
The Football Association has not made any immediate comment about Puncheon's posts, which it may consider brings the game into disrepute.
