Derby County boss Frank Lampard has been charged with improper conduct by the Football Association following Friday’s 2-2 draw at Birmingham City.

“It is alleged his language and/or behaviour on the field of play after [the game ended] amounts to improper conduct,” an FA spokesperson said.

Lampard, 40, has until 18:00 BST on Monday to respond to the charge.

The sixth-placed Rams face play-off rivals Bristol City on Saturday, before Wednesday, 1 May’s trip to Swansea.

The former England international – who is in his first managerial role – was fined £2,000 in September after accepting a charge of improper conduct when protesting against a handball decision.
