(CNN) -- Barcelona moved five points clear in Spain as manager Pep Guardiola celebrated his 100th match in charge with a 4-0 victory at home to Racing Santander on Saturday. 

The injury-hit defending champions brushed off the pre-match loss of star striker Zlatan Ibrahimovic to romp into a 3-0 halftime lead as they put pressure on Real Madrid to win Sunday's home match against Villarreal. 

The Swede is in doubt for Tuesday's Champions League trip to German club Stuttgart due to a swollen ankle. 

Midfielder Andres Iniesta took advantage of some slack defending to pounce for his first goal this season in the seventh minute, hooking home a left-foot effort after the ball ran loose in his 300th outing for the club. 

France striker Thierry Henry, handed a rare start due to Ibrahimovic's absence, netted a free-kick in the 29th minute after driving a shot through the defensive wall for his first goal this year. 

Center-back Rafael Marquez marked his return from suspension with a similar effort nine minute later as he curled a set-piece over the wall and in off the post. 

Barca took their foot off the pedal in the second half, but 18-year-old Thiago scored his first senior goal in the 84th minute with a deflected shot after Lionel Messi set him up with a cutback. 

Captain Carles Puyol had to go off with a facial injury but is expected to face Stuttgart in the first leg of the last-16 tie. 

It was Guardiola's 71st victory since taking charge of the Catalan giants, and 14th-placed Racing never looked like inflicting his 11th defeat -- the 10th came against Atletico Madrid last weekend, Barca's first in La Liga this season.
