Arsenal's close-season signings have added a new dimension to the squad and are helping their team mates reach a higher level, manager Mikel Arteta said after their 6-0 Premier League win over Sheffield United on Monday.

Declan Rice and Kai Havertz, signed from West Ham United and Chelsea in the summer, were among the scorers as Arsenal matched their biggest Premier League away win with a free-scoring display at Bramall Lane.
