What now for Liverpool's back four?

Kolo Toure’s groin injury could force Brendan Rodgers into another defensive signing before the close of the transfer window.

Rodgers’ head would have dropped when the stretcher was called for to carry Kolo Toure off the pitch in the League Cup match against Notts County last night.

The former Arsenal and Manchester City man has been one of the best players for the Reds so far this season, amply filling in for Jamie Carragher who never went back on his decision to retire at the end of last season.

Liverpool now have a problem because while the attack of the squad has been bulked up big time, the defence is currently stretched bare with Toure, Sebastian Coates, Jack Robinson and Aly Cissokho all out of action with various knocks.

There are several options if Rodgers feels he may have to go for one last plunge into the transfer market to try and get some cover.

One of the most obvious additions is Paris Saint-Germain defender Mamadou Sakho who holds a similar status at PSG to Steven Gerrard at Liverpool according to the club's president.

Sakho would be a superb signing for Liverpool if they can get a deal done by the end of Monday, bringing vast experience and quality to the table having already played for France at six different levels.

Liverpool fans will now be very familiar with Tiago Ilori of Sporting Lisbon, a player the club has been linked with for the majority of the summer and a 20-year-old defender Liverpool could still do a deal for.

Ilori is someone Rodgers likes and a player he wants to work with as a first bid of around £3 million suggests. Liverpool have of course made defensive signings since that offer back in May, but it proves how interested Rodgers is in the player.

A better, although more difficult, proposition could be for Liverpool to make an offer to Manchester City for Micah Richards.

However, that would be a completely long term transfer as opposed to a quick fix because the England man is carrying an injury himself, with a hamstring problem that has kept him out of the club’s start to the season.

The same can be said for Schalke’s Kyriakos Papadopoulos, another player linked with Liverpool for most of the summer but another player it would be pointless for Rodgers to sign if he’s looking for some short term cover.

The Greek centre back is out of action following knee surgery, which is always a minefield in terms of the player trying to get fit again.

A more realistic option is Ajax’s Toby Alderweireld, mentioned in Liverpool circles with fans unsure over whether he is worth what would have to be a chunky investment to say the least.

The 24-year-old has made it clear he will only leave Ajax for a big club and Liverpool certainly fit into that category. They can also boast the fact they can offer him immediate first team football in all competitions.

The stumbling block is the rejected bid which has just come in for him by Atletico Madrid. While Ajax seem keen to hang onto him, the rejected offer was due to an insufficient bid which means Liverpool can do a deal for him if they put the right amount of cash on the table.

If Rodgers doesn’t like the look of Alderweireld then Reading’s Alex Pearce is a possible option. The Championship defender was linked with an Anfield switch earlier in the summer before signing a new contract to the end of the 2015 season with Reading.

Therefore, Liverpool would again have to come up with a very big offer because the player and his current club are comfortable with each other, suggesting only a special offer would change that.

What do you think? Should Liverpool go after another defensive signing?
