Arsenal have been told to expect another frustrating game when they go to West Ham for the Boxing Day derby. Home supporters taunted Jose Mourinho with chants of 'boring, boring Chelsea' as Arsenal struggled to create chances against their organised opponents at the Emirates on Monday.
He said: "Arsenal had a very tactical game (against Chelsea). We could do with locking them out like Chelsea did.
"We got tumbled over twice by them last year, particularly at the Emirates, so we'll protect ourselves on Arsenal's abilities and then try to exploit their weaknesses."
