The former midfielder said: “There is a nucleus of a squad there to do well in the Championship – add another six or seven players over the summer and they should dominate.”
The need to revamp the playing squad at Ibrox is one that is evident, especially following the release of over 10 out-of-contract players.
There are few players left who could be considered real first-team quality, and Mark Warburton - who is set to be named manager this week - has a real task to build a squad that can not only compete at Championship level - but actually win the division.
Whilst this lack of players means Warburton will have to undergo a load of work to build a squad in time for the start of the campaign, there is also a benefit to his appointment following the major release of players.
Not only will Warburton be able to sign the players he wants to - rather than utilising those already the club - he can rebuild the playing squad in his own vision and philosophy.
McCall believes that ‘six or seven’ signings will have to be made for Rangers to dominate, but it is not only the number of players that must be brought to the club, but it is their quality that is important.
The club need to ensure that they do not repeat their past mistakes in the transfer market, and Warburton should be focused upon signing quality over quantity as he looks to steer the club back to the Premiership.
