Mersons last Premier League predicitions Result Merses prediction Sunderland 2-1 Man Utd 1-2 Bournemouth 1-3 Stoke 2-1 Crystal Palace 1-2 Watford 2-2 Everton 0-1 West Brom 3-0 Norwich 2-2 West Ham 2-1 Swansea 0-1 Southampton 0-1 Chelsea 5-1 Newcastle 3-0 Arsenal 2-1 Leicester 2-1 Aston Villa 0-6 Liverpool 1-0 Man City 1-2 Tottenham 1-1 Scroll on to see who Merson is tipping this week…Manchester United v Arsenal - 2.05pm, Super SundayBoth sides have had European commitments in midweek but Im not looking too much into that. Im not sure their midweek exertions will have much of an effect and I see Arsenal coming out on top. Merson thinks Olivier Giroud will score as Arsenal beat Man Utd at Old Trafford They are the favourites with the bookmakers and I can understand why when you look at the recent form of both teams. Olivier Giroud is the man Im backing to score first with Arsene Wengers side enhancing their title claims with a 2-1 win at Old Trafford.PAUL PREDICTS: 1-2 (Sky Bet Odds 17/2) Manchester United inflicted a humiliating 8-2 defeat on rivals Arsenal in 2011, with Wayne Rooney scoring a hat-trick West Brom v Crystal Palace - 5.30pm, Saturday Night FootballWest Brom got a great result at Everton but it shocked me to see them lose to Reading in the way they did. However, I dont see them going down because of the Tony Pulis factor. He knows how to keep teams in the Premier League and he will do it again this season. West Brom take on Crystal Palace on Saturday Night Football Crystal Palaces league form has been a worry but their win over Tottenham in the FA Cup would have given them a lift. However, Im going for a 1-1 draw again as Pulis does not lose too many against the sides in and around him. And first goalscorer? Jonas Olsson.PAUL PREDICTS: 1-1 (Sky Bet Odds 9/2) Leicester City v Norwich City - 3pmThese are the games I worry about for Leicester. They are the matches that will define whether they win the league or not. Norwich will go to the King Power Stadium and sit with 10 men behind the ball. They are not going to the Leicester of last season where Norwich would have thought, We can go there and beat them. They are the league leaders. Merse is backing Leicester to beat Norwich 2-1 This is the problem Leicester will have. Can they break down sides with 10 men behind the ball? However, I do think Leicester will win this game. Norwich are on a bit of slump so I think Claudio Ranieris men will win 2-1 and I fancy Jamie Vardy to open the scoring.PAUL PREDICTS: 2-1 (Sky Bet Odds 7/1)Southampton v Chelsea - 3pm Fraser Forster has been a key figure for Southampton in recent weeks Chelsea took a bit of a pasting when these two sides met in the reverse fixture but theyve turned things around since then. This will be a good test to see how far theyve come. Southampton have looked solid and kept a few clean sheets in recent weeks. Its a very hard game to call as I dont see too much between the sides. Ill go for a 1-1 draw with Gary Cahill scoring the first goal.PAUL PREDICTS: 1-1 (Sky Bet Odds 5/
