Sunderland boss David Moyes says January arrival Joleon Lescott has made a big impact.
The centre-half has already earned praise from long-term friend Jermain Defoe, who hailed him as an 'unbelievable' professional.
Moyes said: “He can organise, speak, and tell people where to go, which is maybe something we lacked a little bit at times.
“Joleon's had a massive impact on the dressing room because he's a leader, a really good organiser when he's on the pitch. He's an experienced player, he knows a lot of them as well and he's had a big impact on the dressing room.
“That, in itself, is important. Sometimes it's off the field where you see the impact, not on it."
