Rushed out to Rodriguez's feet in lead up to early goal but could not clear and allowed the striker to fire home. It was an error which cost the home side the game.
Allowed Rodriguez to skip past him in the build-up to Southampton's opener and struggled to redeem himself, with the Saints often getting in behind him as the game progressed.
Much like his central defensive partner Delaney, Dann looked comfortable whenever the ball entered the box and made a number of interceptions.
Coped with the attacking threat of left back Shaw and winger Rodriguez but could not get forward, as he was often pinned back by the away side's numerous forays forward.
Made a number of key early clearances and coped well with the physicality of Lambert, despite allowing the striker to hit the post in the first half.
Full of running in midfield as he looked to pressure the Southampton defense whenever possible. However, the ex-Celtic man struggled to create anything clear-cut, as Lovren and Fonte allowed little past them.
Tasked with protecting the defense but was nowhere to be seen when Rodriguez burst through to score. A display to forget, and he was replaced as Palace chased the game in the second half.
Battled with Shaw throughout and came off second best. Was also at fault for Southampton's opener, as his header towards his own defense allowed Rodriguez to run through. Substituted in the second half.
Tracked Lallana throughout and crunched into an early tackle on the Saints captain, but the England man used his guile and craft to escape the Eagles skipper in the second half.
Grew into the game and beat Clyne a number of times in the second half. His end product was lacking, however, as he often struggled to pick out a red and blue shirt when he reached the by-line. Defended well, though, as he was often forced to track back. Replaced by Thomas in the latter stages.
Picked to lead the line ahead of Cameron Jerome but struggled to cope with the physicality of Fonte and Lovren in the away defense.
Coped well with the copious crosses fired into the box, with his safe pair of hands often reassuring the defenders in front of him.
Tasked with keeping Murray quiet on his return to the starting XI and did so in his own inimitable style, with the striker often bullied into losing possession. Booked in the second half for scything down Bolasie but should have been sent off, as he was the last man.
Pushed forward whenever possible - spending the majority of the first half in Palace's half - and supplied a number of dangerous crosses. His attacking threat was not matched by his defensive ability, however, as he was beaten a number of times by Bolasie in the second half.
Tested throughout the game as Palace attacked down the right flank, but showed his international class as he coped well with the threat posed by Murray and Puncheon. Also provided a genuine attacking threat whenever he crossed the halfway line, with his crosses often finding their intended target. Another dynamic display.
Used his strength to his advantage in the first half and won a number of aerial duels against Murray.
Kept his side ticking over with a number of short passes and also looked to run between the lines whenever the opportunity arose. Was man-marked by Jedinak but often gave the Australian the slip - despite his physical approach.
Played the quarterback role, as he often dropped deep in search of the ball and looked to start attacks with a number of long-range passes. Booked for full-blooded challenge on Jedinak
Linked well with his midfield partners but was forced off in the 33rd minute after picking up an injury, with Wanyama his replacement.
On set-piece duty for the Saints and whipped in a number of dangerous corners, while also nipping at the heels of Jedinak and Dikgacoi in midfield. Replaced by Ward-Prowse in the dying minutes.
Opened the scoring, as he burst forward following a swift counterattack and fired home. Built on his goalscoring start in the second half, with the forward often running beyond the Palace defense in a bid to carve out another goalscoring opportunity.
Picked to spearhead the attack and hit the post in the closing moments of the first half. Linked well with Lallana and Rodriguez, too, and made a number of dummy runs to free up space for his teammates. Replaced by Gallagher in the second half.
