Sunderland defender John O'Shea has spoken of the impact that Sebastian Coates has made at the Stadium of Light since arriving from Liverpool this summer.
The Uruguayan defender has had to bide his time for first-team chances on Wearside, but Coates has had more game time recently and O'Shea has certainly been impressed.
“Sebastian Coates has come in and made a good impression on everyone," he said to the Northern Echo.
Coates was dropped for Sunderland's last match against Aston Villa, which finished 0-0, but prior to that he had starred in their North East derby win.
The loanee came in at the last minute after an injury to Anthony Réveillère in the warm-up, and he stuck to his task brilliantly to help Poyet's men to a 1-0 win over rivals Newcastle United.
A 3-1 defeat to Hull City in their next match saw him slip out of starting line-up, but he has at least proven he can perform a role for the side.
There were worries that Coates was going to be well off the pace after he struggled on his league debut against Manchester City, but faith has grown in his ability.
Coates will now be hoping to play a more vital role for Sunderland in 2015, as they look to climb the table.
The Black Cats' defence has actually been admirable so far this campaign, but going forward they have struggled and their goalscoring threat will need to be improved soon if they are to avoid a relegation scrap.
