Per an FA spokesperson, “Pochettino has been charged with two breaches of FA Rule E3. ... It is alleged the Tottenham Hotspur manager’s language and/or behaviour at the end of the fixture - both on the pitch and in or around the tunnel area - amounted to improper conduct.” Further details on what exactly was said between Pochettino, Dean, and the members of the Spurs coaching staff and the refereeing team are not public information.
The club has until 6 p.m. GMT on Thursday to respond to the charge, though Pochettino said post-match that he would accept any charge that the FA would give him. The possibility exists that Pochettino could face a touchline ban, but considering it is his first time facing a ban or fine from the FA, it is likely the punishment will be smaller.
