Lewis departure 'a shock' - analysis

The timing of Tim Lewis' departure comes as a shock after a hugely successful summer in the transfer market when the vice-chair played an important role.

Lewis has built a relationship with club manager Mikel Arteta and, alongside Andrea Berta, saw through the summer spend of around £250m.

Lewis, a lawyer, is a passionate advocate of financial fair play and has spoken of his concerns about the football regulator.

The 62-year-old is a strong character who is not afraid to say what he thinks, which can lead to uncomfortable conversations.

He is very respected for what he has done during his time at Arsenal and now the boardroom is set to take a new shape, just like the team on the pitch.
