An excellent home debut for Forster, who was largely untested. One excellent save from Brown kept the game even - and proved his class.
Looked solid against the uneffective Anichebe, but found a much more stern test in Brown. Overall, looked comfortable.
Captained Saints marvelously. Marshaled the back four well with a committed performance in the heart of the defence.
Struggled with Berahino on the wing, but supported Tadic well. Early signs of a good spell on the South Coast.
A solid performance but limited in his diagonal crosses into the box. Needed to bomb forward more.
Outstanding. If there's a player to watch out for this season, it's Tadic. Central to the vast majority of Saints' best attacking chances, evoking memories of Adam Lallana's spell at St Mary's.
Looked solid in the middle of the park, and was effective on the ball, linking well with Tadic. Harsh to be hooked at half time.
Hooked in the second half but largely impressive with his effort and passing. A real positive sign for the future, if Saints can hold onto him.
Largely wasteful in his passing and looked to struggle against Mulumbu. Effective in the tackle but needed to offer more of an outlet.
Much was expected from him in this one and he duly delivered. Anchored the midfield well and tried to get forward where possible. Committed performance.
The target man - effective with what he was offered. Little to do with the ball at his feet, but linked well with Tadic.
Had more to do than his goalkeeping counterpart, but provided just one hair-raising moment in a solid performance. Credit to his back four.
Bombed forward well and linked nicely with Berahino, but little to shout about from him today. Defensively solid.
Did well with Olsson at the back, but was second-best in many challenges from defensive corners.
Looked solid overall but could have gifted Saints possession on occasion. Early-season jitters to be expected, but kept a good grasp of his fellow defenders.
Bright and influencing performance from the left-back, who linked well with Brunt. Plenty of overlaps.
The former Sunderland man gave a committed performance in the middle of the park, and even had a few chances to his name. Got forward well and provided great support to the introduced Brown.
A runner's game for him. Full of the stuff, with plenty of gutsy challenges thrown in.
West Brom's midfield general today, and he didn't put a foot wrong. Worked well in the middle and spread the ball effectively into the wings.
Gave Clyne an afternoon to forget with a number of excellent bursts on the left, with a wicked left foot that left Saints' defence flat-footed on a number of occasions.
Looked frustrated all afternoon, as he looked to pluck his best chances from the skies. Needed a runner alongside him.
Did well on the wing but looked like he needed to be up top. A willing runner, but wasted. Found himself largely out of the action.
Came on in the second half and gave a solid account at left back. No complaints.
A late addition to proceedings. Didn't really have time to influence the game.
Could have scored a couple, if only for fine margins. The summer signing looked to offer a real outlet after replacing Anichebe.
