Fabregas set-up Adebayor for Arsenal's sole goal as the Gunners earned a crucial 1-1 away draw with Villarreal in the Champions League quarter-final first leg.

Villarreal will need to score at Emirates in Wednesday's second leg if they are to spring a surprise and book a last-four berth.

The Spanish side's defenders might focus on stopping the threat of midfielder Fabregas and Togolese striker Adebayor, whose combination proved key advantages for Arsenal during their recent league wins.

But Senna, who will miss the game after sustaining a hamstring injury against Malaga on Saturday, believes this will not be the case.

"Adebayor and Fabregas are making the difference for Arsenal at this stage of the season, but we can't just worry about them," the Spaniard, who scored in the first leg, wrote on his blog.

"We have to pay attention to the whole team, we need to mark well and be smart when we have the ball."

"It is important to regain possession quickly, as Arsenal like to keep the ball as well – that's their style."

Villarreal will be looking to avenge their 2006 elimination from the competition's semis at the hands of Arsenal.

"I do think that we can beat them," Senna, 32, added.

"We did it in Greece [against Panathinaikos FC in the first knockout round] and we can do it in London, I am quite sure."
