Michalík managed to establish himself as one of Leeds' first-choice defenders, often partnering Paul Huntington. On 6 September 2008, Michalik was sent off in a match for Leeds against Crewe Alexandra for his second bookable offence. Leeds went on and won the match 5–2. During the middle of the 08/09 season after a number of inconsistent performances Michalik was dropped from the Leeds team by new manager Simon Grayson in favour of new loan signing Richard Naylor. Michalik never regained a starting place and found himself on the bench for the remainder of the season. A role which has continued into the 2009–10 season.
