West Ham United boss Sam Allardyce has sympathy for Aston Villa counterpart Paul Lambert.
Allardyce warned his team against any complacency.
He said: "(Villa manager) Paul Lambert must be wondering what he is doing wrong at the moment, because I watched the game against Tottenham last Sunday and thought how unlucky he was that he lost that game one to a sending off, and two to a deflected free-kick. That seems to happen when things aren't going for you.
"You have to believe in yourself and your team, which he does, to come back, so we have to make sure we try and continue their poor run.
"We will have to be really aware of not leaving too many spaces to let them play that good counter-attacking game that they seem to adapt to well away from home."
