Jamie Redknapp has told The Mail he is uncertain whether Arsenal should put Per Mertesacker back into their first choice XI.
Mertesacker was sent off against Chelsea after fouling Diego Costa, and missed the subsequent game against Southampton through suspension.
He was eligible to return against Bournemouth on Sunday, but instead was left on the bench as manager Arsene Wenger kept faith with Gabriel Paulista alongside Laurent Koscielny.
The pair responded with a clean sheet in a 2-0 win, and Redknapp believes starting Mertesacker against league leaders Leicester City next weekend could be an unwise move.
He said: "Arsene Wenger has a big decision to make. That’s two clean sheets on the bounce without Per Mertesacker. He may be a leader, a World Cup winner and a big presence in the Arsenal defence, but on Sunday, they play Leicester.
"Mertesacker is experienced but one thing he is not is quick. When Arsenal travelled to Leicester they won 5-2, but the big German had a nightmare dealing with the raw speed of Jamie Vardy."
Leicester are five points clear at the top of the table and are full of confidence after beating Liverpool and Manchester City in the last week.
Whether the memories of conceding five against Arsenal is enough to see them alter their game plan to a more cautious style remains to be seen, while if Arsene Wenger does not pick Per Mertesacker for the fixture, it asks questions as to whether he will get the nod against Barcelona later in the month too.
