New signings Jetro Willems and Allan Saint-Maximin trained with their new team mates for the first time on Monday morning.
Both players made eye-catching second-half cameos in Saturday's pre-season friendly win against Saint-Ètienne, just hours after they joined the club on Friday.
Now they will work with the rest of the squad throughout the week ahead of Sunday's first Premier League game of the season against Arsenal. Meanwhile, DeAndre Yedlin and Achraf Lazaar were back in training - Yedlin underwent groin surgery over the summer while Lazaar has recovered from a knock.
