The Wigan captain has urged the Spaniard to move to Anfield should an official offer be made to him by the Reds, praising his manager's calming influence and level-headedness
The central defender praised his current coach and his work with the Latics, insisting that he is capable of managing at a bigger club.
“If the opportunity comes to go to Liverpool, you take it," Caldwell told the Daily Star. "We all understand that. I’m sure he would take it. Nothing fazes him. He stays very calm. Having worked with a lot of Scottish and British managers, you see the tea cups being thrown and stuff. But he’s from Spain and it’s a different culture and mentality and he remains very calm. At half-time during games it’s me, Shaun Maloney and James McArthur going mental and he just tells us to sit down and relax, goes through things calmly and that helps us to get results."
It is this approach that Caldwell believes makes Martinez more than capable of taking the reins at a bigger club.
“He has what it takes to manage a club such as Liverpool," the center back asserted. “If that big job comes now then he has to go and show he is good enough. Having worked with him and knowing his tactical awareness and the thought he puts into training, then who knows what he could go on and achieve at a big club like Liverpool with their resources? It’s been great for me to play under him."
Caldwell also highlighted the change of tactics in the turnaround of Wigan’s fortunes in 2011-12 and admitted that it had been a lot of hard work but expressed his delight at their results in avoiding the drop from the Premier League.
“Roberto moved to a three-at-the-back system around November in a game against Blackburn. We drew 3-3," he continued. "It took us a long time to get it as good as it got. Not many teams play 3-4-3 and it was a bold move. It took hard work on the training pitch from the summer time. The system suited us."
“When we signed Jean Beausejour to play at left wing back that helped with the balance. It suited the strengths and weaknesses of the players. A lot of good managers couldn't cope with it. A few said Sir Alex Ferguson didn't really know how to stop us the night we beat them [1-0]. They couldn't stop us. It was a great credit to the players.”
