the bavarians , chasing three titles this season , are without arjen robben , franck ribery , bastian schweinsteiger and david alaba among others for the quarter-final , first leg in portugal .
` for the -lrb- recent -rrb- games against borussia dortmund and bayer leverkusen we had two matches where we played with a decimated squad and with few options , ' muller said .
they also beat eintracht frankfurt 3-0 on saturday .
` in those games we came closer together as a group , as a unit , and that will obviously help us against porto .
