Manchester City clearly had one eye on the Champions League semifinals. It came at the expense of their chances to remain in the competition next year.
The visitors at St. Mary’s had the opportunity to lock up Champions League play next season with all three points, but instead Manuel Pellegrini rested a number of starters including Sergio Aguero and Kevin De Bruyne, and Southampton ripped them apart in a 4-2 win. Saido Mane grabbed a hat-trick and Dusan Tadic had a trio of assists as their attack swarmed a mistake-prone and clearly distracted Manchester City.
Both sides had spells in the opening 20 minutes, but Southampton appeared more dangerous. Shane Long made multiple appearances in front of the Manchester City goal, picking the pocket of Pablo Zabaleta to earn a corner on 15 minutes and shooting just wide of the near post in the 19th minute.
Frasier Forster was required to keep the game scoreless in the 20th minute as Kelechi Iheanacho stole the ball from Virgil van Djik on the touchline and found Raheem Sterling in space inside the box, but his shot was saved expertly by Forster.

It would be the in-form Long to take the lead in the 25th minute on a beautiful bit of play. A fantastic ball over the top of the City defense fell to a streaking Dusan Tadic, and his flick over the top met a sliding Shane Long, who beat Nicolas Otamendi for the opener.
They’d get a second just four minutes later on yet another sweet-looking goal, with Tadic getting yet another assist with a perfectly weighted ball for Saido Mane, who smacked it by Joe Hart from a tight angle.

Southampton continued to press and hold much of the meaningful possession, but Manchester City refused to capitulate, scoring a lifeline before halftime. With the ball in the Southampton penalty area, Cuco Martino saw the ball skip off his thigh and pop into the air, where Iheanacho latched onto it and headed it into the net.

It was a tough way for the hosts to go into halftime, as they had dominated much of the first half, but no matter, as they made amends. Following the break, Southampton restored their two-goal lead off a corner in the 57th minute as Van Djik’s header was tipped by Joe Hart off the crossbar. Jose Fonte whiffed at the rebound but Mane was there from point blank range to give Southampton a 3-1 lead.
Mane would complete his hat-trick in the 68th minute. Van Djik won the ball in the Southampton half to start the break, and Tadic picked up his third assist of the match as he slotted Mane through on goal for yet another clinical finish.
Manchester City got another back as Iheanacho bagged his second in the 79th minute with a wonderful curler from outside the box, but it was too little too late for the visitors.
Both teams fought until the final whistle, and it could have cost Jesus Navas his fitness as the Spaniard seemingly picked up a serious limp in the final few minutes.
