Grammar - relic or integral part of teaching English?

University students nowadays are well equipped with language knowledge. The main weak point which remains is grammar. What is more, students often show repugnance for grammar, which results from endless drilling exercises and boring theoretical lessons. Teaching grammar is necessary as our students are exposed to English only during lessons, so they are not likely to acquire grammar just through listening to and absorbing English. As they live in the Czech environment, the tendency to combine English vocabulary with Czech grammar rules is getting stronger. Grammar lessons should not just consist of presentation of particular rules. Each rule should be shown as a part of logical grammatical system. I also recommend to compare Czech and English systems. Practising grammar has to become an integral part of teaching Process. There must not be any contrast between teaching grammar and practising communication skills.
