William Gallas is concerned by Kai Havertz‘s start at Arsenal, and feels his former club made a ‘mistake’ signing the Germany international this summer.

After three years at Chelsea which saw him win the Champions League and Club World Cup, Havertz joined Arsenal for £65m in July.

Havertz has featured regularly for Mikel Arteta‘s men in the opening weeks of the season, but has struggled to nail down a position in the side and only has one goal to his name so far – a penalty in a routine 4-0 win against Bournemouth.

Former Arsenal captain Gallas has not been convinced by Havertz and believes he is yet to make a positive impression at the Emirates.

‘I’m not impressed with Kai Havertz so far,’ he told Lord Ping. ‘He’s done nothing since he joined Arsenal.

‘He may have scored, but that was only because Martin Odegaard let him take a penalty! Havertz hasn’t done anything yet, and I think he’s in trouble.’

Arsenal beat Manchester City before the international break to move level on points with north London rivals Tottenham at the top of the table.
