Coleman insists midfield pivot Allen has the mentality to come back stronger for Brendan Rodgersâ€™ men.
Coleman told the Daily Star Sunday: â€śHeâ€™s playing for Liverpool now and that jersey is Âheavier. They are used to winning Âtrophies so if youâ€™re not winning games then criticism will come.
â€śBut heâ€™s got a good mentality, heâ€™s very level-headed and has a steely character. One million per cent. He wonâ€™t shy away. He may be having a dodgy patch but if you watch him play, he will still go Âlooking to receive the ball and keep doing what he is good at.
â€śLiverpool have also had down times as well. People donâ€™t talk about Steven ÂGerrard because he is an institution. They wonâ€™t attack him or Jamie ÂCarragher.
â€śThey will attack the new players. When Lucas signed, he didnâ€™t have it all his own way.
â€śThey like him now Âbecause heâ€™s been there a while. But heâ€™s had to earn it and Joe will have to do the same.â€ť
