Bayern Munich were made to work hard for more than an hour before battling past hosts Werder Bremen 2-1 to go provisionally four points clear at the top of the Bundesliga with three games left to play. Second-half goals from Serge Gnabry and Leroy Sané gave Bayern their second win in their last four league matches to move up to 65 points, four ahead of Borussia Dortmund, who have four matches left to play and host Wolfsburg on Sunday. Bayern, who only have the Bundesliga left to fight for after their DFB-Pokal and Champions League exits in recent weeks, had Werder on the back foot from the start but despite their possession they lacked the final punch in front of goal. Bremen, without injured Bundesliga top scorer Niclas Füllkrug, gradually found their footing but struggled to convert their chances, with Christian Gross missing their best effort after firing wide following a fine solo run. Bayern, chasing a record-stretching 11th straight league title, perfectly executed a quick passing move in the 56th minute but Sadio Mané sent Gnabry’s cutback wide. The roles were reversed more successfully six minutes later with the Senegal international crossing into the box and Gnabry slotting in for the lead. The goal instantly took a load off Bayern’s shoulders and substitute Sané cut into the box from the right to drill in their second. Werder’s Niklas Schmidt injected some late drama into the game when he blasted the ball past Yann Sommer and into the top corner in the 87th minute to cut the deficit. Milan secured a much-needed 2-0 home win against Lazio but suffered an injury scare four days before their Champions League semi-final first leg against Internazionale, when Rafael Leão had to go off in the early Serie A game. Inter then returned to fourth place, two points clear of their neighbours, with a victory by the same score at Roma. Leão suffered an apparent thigh injury 11 minutes in, but Milan’s coach, Stefano Pioli, played down its severity. “I just saw him, he was calm and feeling good,” Pioli said. “I honestly don’t think, based on what he told me, that it’s a particularly serious thing.” His team shrugged off Leão’s loss, Olivier Giroud soon taking advantage of a Lazio defensive error to set up Ismaël Bennacer for the midfielder to bundle the ball past Ivan Provedel in Lazio’s goal. Theo Hernández then delighted the San Siro crowd when he lobbed Provedel with a superb shot from distance to double the lead for Milan just before the half-hour mark. The France international sped through the entire pitch to finish off an impressive solo effort, which started right outside Milan’s own box. A disciplined Milan side continued to dominate after the break and the half-time substitute Malick Thiaw could have made it 3-0 after connecting with a corner, however, his header went narrowly over the bar. Maurizio Sarri’s visitors showed more intent late in the game and Luca Pellegrini was close to pulling a goal back but could only find the side-netting with his close-range shot – indeed Lazio, who suffered their third loss in four Serie A games, did not manage a shot on target. They stay second in the standings and have a one-point advantage over Juventus, who travel to Atalanta on Sunday. The midfielder Federico Dimarco and striker Romelu Lukaku were both on target as Internazionale secured a 2-0 victory at Roma, their fifth consecutive win in all competitions. The Inter defender Denzel Dumfries squared the ball inside Roma’s six-yard box and Dimarco was in the right place to tap it in from a tight angle just after the half-hour mark. Lukaku sealed the win in the 74th minute with a low strike from the edge of the box after an error by Roma’s defence gifted the ball to the visitors.
