Former Rangers attacker Gordon Smith believes Philippe Senderos could have the same effect that David Weir had on the Gers defence in the latter stages of his career.
The 31-year-old defender joined the Ibrox club on transfer deadline day after boss Mark Warburton failed in his bid to land centre-back Joleon Lescott from Aston Villa.
After featuring in a testimonial match against Linfield in Belfast on Saturday, Senderos, capped 57 times by Switzerland, is expected to make his competitive debut in the first big Glasgow derby of the season at Celtic Park on Sunday.
Smith, who had spells at Rangers in the 1970s and 1980s, claims the former Arsenal, Fulham, Valencia and Grasshopper player could have the same impact as current assistant manager Weir, who spent almost five years at Ibrox after moving there as a 37-year-old in 2007.
Speaking to Sky Sports News HQ, Smith, a former Scottish Football Association chief executive, said: “He (Senderos) is a very experienced player and sometimes if you bring in a player like that it can help.
“David Weir is a great example of that. He came into Rangers in the latter part of his career and did a fantastic job and Senderos may be able to do that kind of job too.”
Brendan Rodgers’ Celtic side will go into the game as favourites, having won their first three Ladbrokes Premiership games to sit top of the table, one point above Rangers with a game in hand.
However, Smith played down the importance of form in derby games.
The former Kilmarnock and Brighton player said: “You can’t take anything for granted.
“You never know how it will go in these games.
“Even myself during my time playing against Celtic teams, it’s the occasion that matters and how teams respond to the occasion as opposed to the opposition.”
