Differential: [adjective] a fantasy football term relating to a player with a low picked percentage, who offers equal points potential compared to the more popular players.
A differential gives a fantasy football manager an alternative when selecting their team. Due to a player's low selection percentage, when a differential scores highly a manager will see their fantasy football team significantly rise up the rankings.
Fantasy football game www.oulala.com boast a scoring matrix comprised of 70 different statistical criteria. Using their extensive database of stats, Oulala have identified four players that will offer your fantasy football team alternative options that you may not have considered.
Goalkeeper
While many fantasy football managers sit aboard the Petr Cech bandwagon, there is another keeper seemingly going relatively unnoticed in the fantasy football world.
Stoke City's Jack Butland has been winning rave reviews this season and after his most recent performance against Newcastle last weekend it's no surprise why. Oulala's stats show that the 22-year-old pulled off six saves and made seven successful claims at St James' Park on Saturday helping Stoke to a well-deserved clean sheet in their 0-0 draw.
Despite keeping only three clean sheets from a possible 11 games, Butland's individual efforts are to be admired. His 37 saves have seen Butland make a save, on average, every 27 minutes. With 43 successful claims from a possible 44, Butland boasts an excellent success-rate of 98 per cent.
In any other season, many would hold off from picking a keeper with a game against Chelsea on the horizon, but this isn't any other season. Chelsea are having a torrid time and Butland will be looking forward to the challenge of heaping yet more misery on the champions. With the return of skipper Ryan Shawcross to Stoke's defence too, Butland offers an excellent alternative to the usual suspects.
Defender
Vincent Kompany, Aleksandar Kolarov and Bacary Sagna are popular fantasy football picks this season, and rightly so. Manchester City have kept six clean sheets in their opening 11 games.
However, one man currently sits off most fantasy football radars. New recruit - Nicolás Otamendi.
Against Norwich last weekend, Otamendi was one of City's standout players netting the opening goal. The Argentine also completed 64 successful passes with an accuracy of 91 per cent. The five tackles that he won was the most by any City player. He also won five aerial duels, again more than any of his team-mates. The 11 clearances he made was more than double any other City player managed.
According to Oulala's stats - which cover a host of other European leagues - Otamendi was La Liga's top scoring defender last season with six goals. The Argentine already has one to his name in the Premier League this season, with more likely to follow judging by his ability in the air.
A game against a struggling Aston Villa this weekend presents a great opportunity to feed the Argentine into your fantasy football side as a great alternative to the more popular and currently less influential City defenders.
Midfielder
Southampton's Dušan Tadić has continued his excellent form from last season into this campaign. The Serbian has been overshadowed by team-mates Sadio Mané and Graziano Pellè this season.
In his side's 2-0 win over Bournemouth on Sunday, Tadić registered an 84 per cent pass completion, provided two key passes and an assist.
In contrast, his seasonal stats have been just as impressive. The 26-year-old has scored two goals, provided three assists and created a mouth-watering 31 chances for team-mates. An overall pass completion of 78 per cent along with 28 key passes this term highlight how influential Tadić has been for Southampton.
The Saints visit an out-of-sorts Sunderland this weekend and the Serbian is an interesting alternative to the more popular Sadio Mané.
Striker
Jürgen Klopp registered his first Premier League win as Liverpool manager last weekend in an impressive 3-1 victory away at Chelsea. Striker Christian Benteke was on the score sheet to register his fourth goal in eight games for the Reds this season.
While many fantasy football managers appear to be opting for Everton's Romelu Lukaku or Southampton's Graziano Pellè, both of who are in good form, they offer little difference with the masses who are already aboard.
Under a new manager, Christian Benteke could go on to surpass other popular strikers in the Premier League this season.
The Belgian has netted four goals from just 16 shots giving him an impressive conversion-rate of 25 per cent. While Benteke's shot accuracy sits at a healthy 58 per cent.
Liverpool will be looking to follow up their win at Stamford Bridge when they host Crystal Palace on Sunday.
If you're looking for a striker with a proven track record for your fantasy football team - look no further - Benteke's your man.
