The Baggies goalkeeper was mesmerised by the Belgian‚Äôs impact as he scored a second-half hat-trick in the incredible 5-5 draw with champions Manchester United yesterday.
And he reckons it will be the last time Lukaku runs out in Albion colours.
‚ÄúThere‚Äôs no way he‚Äôs coming back here next season,‚ÄĚ said Foster.
‚ÄúChelsea would be fools to let him come back with the way their forward line is misfiring, he‚Äôs exactly what they need at the minute.
‚ÄúHe has come on and changed it. Fair play to him.
‚ÄúHe was unplayable. As soon as he came on you could see that they were physically scared of him. He dominated everything that came his way. It was a fitting send-off for him.
‚ÄúHe‚Äôs done so much for us and I‚Äôm really happy for him because he‚Äôs such a nice lad.‚ÄĚ
