Lionel Messi and Ansu Fati led the way for Barcelona as Quique Setien's men did just enough to claim a 2-1 win over Levante at Camp Nou on Sunday, moving them back to within three points of leaders Real Madrid.

After a remarkable breakthrough at the start of the season, Fati had recently come in for criticism amid some underwhelming displays, but he showed just how effective he can be as Messi carved open the Levante defense.

Fati took his top-flight tally to four with a pair of strikes separated by just 102 seconds in the first half, profiting from the brilliance of Messi on both occasions to become the youngest player to score a LaLiga brace this century.

Levante offered a lot more from an attacking perspective after the break and deservedly pulled one back through Barca academy product Ruben Rochina in stoppage time, but Fati's efforts had put the game beyond the visitors, despite a hat-trick ultimately eluding the 17-year-old.

After easing their way into the contest, Barca crafted a flurry of chances after the 13th minute – Messi shooting agonizingly wide and then testing Aitor Fernandez, before Antoine Griezmann prodded just off target.

Levante were eventually breached after half an hour as Messi fed Fati with an exquisite through ball and the teenager clinically slotted home.

The same pair combined again less than two minutes later, Fati this time firing through the legs of the unconvincing Fernandez.

The lead should have been extended before half-time, but Nelson Semedo hit the crossbar and Griezmann inexplicably missed from inside the six-yard box.

Barca were fortunate to not concede early in the second half – Jose Luis Morales galloping through on goal and seeing his effort saved by Marc-Andre ter Stegen, with Rochina hopelessly blazing the rebound over.

Fati was not far off getting a third in the 73rd minute when his overhead-kick went just past the left-hand post, while Levante finally got on the scoresheet soon after wasting two fine chances – Rochina's strike hitting Ter Stegen and going in.

What does it mean? A welcome win but defensive concerns remain

Barca were abysmal in their previous LaLiga match, the 2-0 defeat at Valencia that preceded the Copa del Rey demolition of Leganes.

In Mestalla they left a lot to be desired at the back and again they failed to keep a clean sheet on Sunday, with those concerns still prominent. Levante could – and arguably should – have had more than one goal to show for their efforts.

Fati gets a timely boost

It would be unfair to be too harsh on a teenager, particularly considering he is obviously talented, but Fati's impact of late had been minimal. On Sunday, however, he was lively, intelligent with his movement and a creative outlet, providing three key passes on top of his two goals.

Griezmann is no Suarez

Luis Suarez was always going to be tricky to replace, even for Griezmann. There were hints of promise in the first half as the Frenchman got into some good positions, but he wasted one particularly good opportunity. None of his three shots were on target and he did not create any chances either – Suarez is often productive on both fronts..

What's next?

Barca return to Copa del Rey action on Thursday at Athletic Bilbao, before heading to Seville to face Setien's former club Real Betis in LaLiga three days later. Levante host Leganes on Saturday.
