Southampton manager Ralph Hasenhuttl has described Jack Grealish's anger with Oriol Romeu that saw him wait in the tunnel for the Spanish midfielder.
The 26-year-old was a constant danger throughout proceedings at St Mary's and became a target for the Saints who fouled the England international on three occasions.
The sides shared the spoils as Kyle Walker-Peters' first-half strike was cancelled out by Aymeric Laporte in the second half, putting an end to City's 12-match winning run.
