It’s easy to start changing what you should do and start playing balls centrally through areas that are compact.“We stuck to our plan though, and I’m really pleased we did that.” Sky Sports presenter apologises for remarks made during Neville’s racism discussion “If we want to get to where we want to get too then those are things we definitely need to improve, but in terms of performance, spirit and effort from the group I’m delighted with them today – it’s a huge three points for us.”Meanwhile, Chelsea are assessing an ankle injury that midfielder Ross Barkley suffered against the Magpies.The 25-year-old went off shortly before half-time at Stamford Bridge, and Lampard said after the game he was unsure whether Barkley is likely to be available for Wednesday’s Champions League clash in Ajax.“Ross has turned his ankle and it looks a bit nasty at first glance but the doctor wants to have a look tomorrow, so I’ll know more then,” he explained.
