Alli has now had a hand in 11 goals in his last 14 Premier League games for Spurs (six goals, five assists). Ozil was also on the scoresheet at the weekend, taking his tally to four for the season. However, its in assists that the Arsenal man really stands out. He has recorded a Premier League-high 16 assists so far this season and created a remarkable 100 chances for his team-mates.Silva is also a top chance-creator, conjuring up 44 opportunities for Man City, and has been involved in 10 goals so far this season.
