The FA Cup returned on Saturday but there was not much magic to celebrate. Manchester City coasted past Burnley, Watford knocked out Newcastle and Wolves denied Shrewsbury a famous cup upset. Here, Sportsmail brings you all the things you might have missed from all of Saturday's FA Cup action. Manchester United boss Ole Gunnar Solskjaer took the afternoon off to check in on their rivals City on Saturday. The Norwegian was spotted in the stands as City put Burnley to the sword to progress into the next round of the FA Cup. City are potential opponents in the fifth round with United earning their place in the hat after beating Arsenal on Friday evening. It could also have been an early scouting mission, with Solskjaer's men scheduled to take on City in the Premier League in the middle of March. You don't see this everyday but the corner flag had to substituted after picking up a pretty nasty injury. Kyle Walker snapped the flag in half as he tried to cross into the box during the first half of Saturday's FA Cup clash with Burnley. The match was delayed for a couple of minutes as the linesman tried to fix the flag, but luckily, City's head groundsman Lee Jackson was on hand and came to the rescue by running down the tunnel to grab a new one. City confirmed after the match the flag has been forced to retire from its duties at the Etihad due to the injuries. Millwall manager Neil Harris was spotted screaming to the stands to get the replay of their second equaliser off the big screen after it clearly showed the ball had come off Jake Cooper's arm. The defender levelled the scores in the second half shortly after Everton had taken the lead after the ball luckily ricocheted in off him after Jordan Pickford had saved with his legs. The Everton players appealed for hand ball but the goal stood. Everton boss Marco Silva complained to the fourth official after seeing his players were right to be aggrieved when the replay came up on the big screen. Desperate times call for desperate measures. That must have been what was going through Sean McConville's mind when he decided to chuck himself to the ground in attempt to win a penalty. With the seconds ticking down and Accrington Stanley staring at an FA Cup exit, McConville tried to con the referee. The problem was Derby defender Duane Holmes appeared to have anticipated it and pulled out of his sliding challenge as the Accrington player went down. Holmes wasn't best pleased. McConville, on the other hand, allowed himself a wry smile at how wrong his attempt had gone. Somehow he avoided a booking. Derby goalkeeper Kelle Roos clearly seems to just love diving round. The Dutchman on two occasions during Saturday's game dived when the ball had already gone past him. People on social media were quick to spot it with one person writing on Twitter: 'Looks like the Derby keeper is suffering with 'FIFA lag'!' A mass brawl broke out between QPR and Portsmouth players threatened to overshadow their FA Cup clash on Saturday. A tussle between QPR's Josh Scowen and Pompey's Ronan Curtis sparked a mass melee with all 22 players getting involved. Arms and elbows were flying around from several players as the match officials tried to calm the situation down. Three players received yellow cards in the end. Shrewsbury's Ollie Norburn read a note from his pants before delivering a peach of a cross for their second goal against Wolves. The midfielder took the note out and quickly scanned over it before putting it back down his pants and whipping in a corner for Luke Waterfall to head in. It seemed as if an upset was on the cards but Premier League side Wolves came from two down and struck a late equaliser to take it into a replay.
