Rangers are sure to sign more players in the January transfer window.
Johnstone said: “Mark will already have his targets in mind for January to freshen up the team and the squad and there will be players coming in next month. They will need to be better than what we have at the moment because we need to improve the team, not the squad.”
Despite starting the season in excellent form, Rangers have been struggling in recent weeks.
They lost their first league game to title challengers Hibs, and have drawn two of their last four games, and it appears as if Warburton’s squad has now reached it’s natural level after flying high in the opening weeks of the campaign.
There is talent there, but the lack of a consistent goalscorer to compete with Martyn Waghorn is letting the team down, and Johnstone has urged Warburton to sign players who improve the team, not the squad, in January.
A new striker is needed, whilst a more physical holding midfielder would not go amiss. Warburton could also look at bringing in a central defender to compete with Dominic Ball, Rob Kiernan and Danny Wilson, who have all struggled at various times this season.
Signing players to improve the strength in depth would be wise if Rangers were flying high and had already assured promotion. They could spend money risk free, knowing that they were building for next season.
However, they need to bring in players who improve the first-team, and Warburton should already be lining up signings with two weeks to go before the transfer window opens.
