TIP 1: Martin Odegaard - Over 1.5 Shots - 1pt

Best odds of 19/20 at William Hill while publishing.

Ødegaard's shot volume has been relatively modest across his recent Arsenal appearances, but the line is still within reach given his tendency to find shooting opportunities from the edge of the box. He has recorded 3, 2, 0, 1, 1, 1, 0, 2 and 2 shots across his last nine games for Arsenal, clearing the 1.5 line in three of those matches.

His World Cup numbers also show that he is capable of becoming more aggressive in front of goal when given greater attacking responsibility, with 1, 3, 1, 3 and 1 shots across his five matches. Against an opponent likely to defend for periods and concede possession, Ødegaard should have opportunities to arrive around the box and test the goalkeeper.

TIP 2: Christos Tzolis - Over 2.5 Shots - 1pt

Best odds available of 1/1 at Virgin Bet while publishing.

Tzolis has developed into one of his side's more willing shooters, and his recent numbers make the over 2.5 shots line particularly interesting. He has exceeded 2.5 shots in six of his last 10 games, with his last 10 shot counts reading 4, 0, 2, 2, 5, 2, 3, 3, 7 and 1.

That includes three games with at least three shots in his last five, while the seven-shot performance demonstrates the ceiling he possesses when he finds space in the final third. With Tzolis expected to remain heavily involved in his side's attacking transitions, he should have opportunities to get the required attempts away.

TIP 3: Boubacar Kamara - To Be Shown A Card - 1pt

Best odds of 17/5 at Sporting Index while publishing.

Kamara's recent disciplinary record makes this an interesting card angle. He has been shown a card in two of his last six games, while his foul counts across his last six Premier League appearances stand at 2, 0, 2, 1, 2 and 2.

That means he has committed at least two fouls in four of those six matches, underlining his willingness to engage in midfield challenges. The referee adds another layer of interest, with Jarred Gillett averaging 4.03 cards per game. If Kamara is forced into repeated defensive situations against an attack looking to progress quickly through midfield, the conditions could be favourable for him to enter the referee's book.

7/2

TIP 4: Valentin Rosier - Over 0.5 Shots - 1pt

Best odds of 23/20 at Ladbrokes while publishing.

Rosier has been remarkably consistent in getting an effort away, exceeding 0.5 shots in eight of his last 10 games. His shot counts across that run are 1, 1, 3, 0, 0, 1, 1, 1, 3 and 2, with at least one attempt in eight of those matches.

For a player who is not necessarily expected to be a primary attacking outlet, that level of consistency makes the 0.5 line appealing. Rosier's willingness to support attacks and take up advanced positions gives him opportunities to get a shot away, and he only needs one attempt to clear this market.

TIP 5: Lamine Yamal - Over 0.5 Assists - 1pt

Best odds of 17/10 at 10bet while publishing.

Yamal has had a relatively quiet start to the season by his extraordinary standards and will be eager to get involved on the scoresheet. The Barcelona winger produced 17 assists last season, highlighting the quality of his final ball, while he averaged 2.6 key passes per game in La Liga.

That creative output makes the over 0.5 assists line particularly interesting. Yamal does not need to score to influence the game, with his ability to create chances from wide areas, combine around the box and deliver the final pass providing multiple routes to an assist. Given the volume of chances he is capable of creating, this looks like a good opportunity for Yamal to open his assist account for the season.
